   we now have pcmanfm + gvfs - does anybody know how to mount devices as user?

   pcmanfm+gvfs+udisks I know how it works http://www.ab9il.net/linux/pcmanfm-usb-mount.html

   but without udisks?

   ok - it works, but only for usb - devices

   open a terminal (sakura) and get root

   leafpad /etc/polkit-1/localauthority/50-local.d/55-storage.pkla

   copy the following lines into the file

   [Storage Permissions]
   Identity=unix-group:plugdev
   Action=org.freedesktop.udisks2.filesystem-mount;org.freedesktop.udisks.drive-eject;org.freedesktop.udisks2.drive-detach;org.freedesktop.udisks2.luks-unlock;org.freedesktop.udisks2.inhibit-polling;org.freedesktop.udisks2.drive-set-spindown
   ResultAny=yes
   ResultActive=yes
   ResultInactive=no

   safe and close and then type

   addgroup tux plugdev

   close X and start it new

   if you want to mount also internal devices as user, 55-storage.pkla should look like this

   [Storage Permissions]
   Identity=unix-group:plugdev
   Action=org.freedesktop.udisks2.filesystem-mount-system;org.freedesktop.udisks2.filesystem-mount;org.freedesktop.udisks2.drive-eject;org.freedesktop.udisks2.drive-detach;org.freedesktop.udisks2.luks-unlock;org.freedesktop.udisks2.inhibit-polling;org.freedesktop.udisks2.drive-set-spindown;
   ResultAny=yes
   ResultActive=yes
   ResultInactive=no

   the only thing, I cannot eject the CD, where slitaz booted...

   I just set the topic to not resolved, because I do not find a solution to mount/umount-eject CDs

   first strange thing: pcmanfm does not print anything when opend with terminal, so I dont get any messages.

   The only thing I could find was in messages:

   Apr 28 19:50:08 (none) daemon.warn udisksd[1410]: Error opening /etc/crypttab file: Failed to open file '/etc/crypttab': No such file or directory (g-file-error-quark, 4)
   Apr 28 19:50:08 (none) daemon.notice dbus[1327]: [system] Successfully activated service 'org.freedesktop.UDisks2'
   Apr 28 19:50:08 (none) daemon.notice udisksd[1410]: Acquired the name org.freedesktop.UDisks2 on the system message bus

   Apr 28 19:57:50 (none) daemon.warn udisksd[1410]: Error opening /etc/crypttab file: Failed to open file '/etc/crypttab': No such file or directory (g-file-error-quark, 4)
   Apr 28 19:57:50 (none) daemon.notice udisksd[1410]: Mounted /dev/sr1 at /run/media/tux/SliTaz core-4in1 on behalf of uid 1000
   Apr 28 20:00:41 (none) daemon.warn udisksd[1410]: Error opening /etc/crypttab file: Failed to open file '/etc/crypttab': No such file or directory (g-file-error-quark, 4)
   Apr 28 20:00:41 (none) daemon.notice udisksd[1410]: Cleaning up mount point /run/media/tux/SliTaz core-4in1 (device 11:1 is not mounted)
   Apr 28 20:00:41 (none) daemon.notice udisksd[1410]: Unmounted /dev/sr1 on behalf of uid 1000

   so the SliTaz CD is unmounted, but eject is denied

   and when I put a CD in a second device - there is nothing to find

   perhaps somebody has an idea....

   Hi kultex
   to mount as user without "Not Authorized" message I use this one without
   adding tux to plugdev-group

   add the file /etc/polkit-1/localauthority/50-local.d/50-mount.pkla

   [Mount a system-internal device]
   Identity=*
   Action=org.freedesktop.udisks2.*
   ResultAny=yes
   ResultActive=yes
   ResultInactive=yes

   It work with Hdd and USB but with CD I have some Problems too.CDs (Drives)
   don't show up in pcmanfm when i insert a CD.If I mount them in terminal,(su to root), to /media/cdrom they are visible and accessible in pcmanfm (for tux)and surprise,surprise
   I can eject them with a rightclick on the Icon (as tux),
   but not with the eject-button at the CD-Drive
   F**k

   I solved inserting a CD

   it needs kernelpolling - as root

   echo 5000 > /sys/module/block/parameters/events_dfl_poll_msecs

   to make it permanent, add this line to /etc/init.d/system.sh or /etc/init.d/local.sh

   Edit: found something to try

   Identity=unix-group:plugdev
   Action=org.freedesktop.udisks2.filesystem-*;org.freedesktop.udisks2.eject-*
   ResultAny=yes
   ResultInactive=yes
   ResultActive=yes

   mixed results:

   -->found something to try<---
   makes no difference: Hdd = yes, Usb = yes, CD = does not show up
   (yes, i did addgroup tux plugdev..;-)

   using your new file and adding in terminal
   echo 5000 > /sys/module/block/parameters/events_dfl_poll_msecs

   The CD shows up in pcmanfm BUT rightclick > eject = Not authorized...The eject-button at the CD-drive is now working but pcmanfm doesn't notice that the CD is gone,
   still showing the content.

   Part 2

   using my file and your echo 5000 line:
   the CD shows up, rightclick > unmount work, CD-drive eject button work,
   BUT rightclick > eject doesn't work no more.The CD stops and I get this error message:

   Error ejecting /dev/sr0: Command-line `eject "/dev/sr0"'
   exited with non-zero exit status 1:
   eject: /dev/sr0: Input/output error

   This is not "Not authorized" ...

    When booting to the desktop with a live cd an unknown process mounts the live cd.
    Busybox eject doesn't run umount prior to eject, and reports input/output error on failed eject.
    Util-linux-eject umounts prior to ejecting is a workaround.
    Stopping whatever is auto mounting the cd is a better solution.

    @mojo I think its not unknown - its udev, that does all the mount things - if I add kernel polling before I enter a CD in the second CD-Rom it shows up in pcmanfm, but I cannot mount it as user, because there are no polkit rools.

    So this means that we are also stuck here in the ash / bash problem - what soulutions do we have - I see two

    1) solution - we get pcmanfm to use Util-linux-eject (I dont think so)

    2) solution - we remove the udev CD rules and write our own udev rules to mount CD/DVD via fstab - then when I quote sixofeights lines - "If I mount them in terminal,(su to root), to /media/cdrom they are visible and accessible in pcmanfm (for tux)and surprise,surprise I can eject them with a rightclick on the Icon (as tux)" - it should be possible to eject.

    somebody sees another solution?

    The fstab thing reminds me, that salckware / porteus did this - I just posted it here:

    http://forum.slitaz.org/topic/udev-changes-for-50#post-26835

    the important file is the udev-fstab-update.txt (last attachment - the first attachment is not working)

    struggling around the whole day with this s..t and the only thing is that you just have to install util-linux-eject and evrything is working fine

    Hi there!

    My current SliTaz system is so far from latest Rolling, but it also based on the Cooking packages. And I fairly want to test brand new Rolling included all the latest improvements! Sad, but on mirror I can find only Rolling dated April, 27.

    So. On my current system. Reading system logs:

    /var/log/messages:
    May 1 10:18:24 (none) daemon.err udevd[930]: failed to execute '/lib/udev/udisks-part-id' 'udisks-part-id /dev/mmcblk0': No such file or directory

    A lot of lines like above. Looking at pkgs.slitaz.org I found that udev package have only /usr/lib/udev/udisks-part-id, so I symlinked it to /lib/udev/udisks-part-id.

    And a lot of lines like this:
    May 1 10:18:43 (none) daemon.warn udisksd[1263]: Error opening /etc/crypttab file: Failed to open file '/etc/crypttab': No such file or directory (g-file-error-quark, 4)

    So I just touched empty file /etc/crypttab.

    Now, my USB Flash. It has two partitions. Maybe something wrong with its FS, but now I can see only one partition. Here is "fdisk -l" about it:
    

    Disk /dev/sdb: 8103 MB, 8103395328 bytes
    250 heads, 62 sectors/track, 1021 cylinders
    Units = cylinders of 15500 * 512 = 7936000 bytes
    
       Device Boot      Start         End      Blocks  Id System
    /dev/sdb1               1        1016     7871488  1b Hidden Win95 FAT32
    Partition 1 has different physical/logical beginnings (non-Linux?):
         phys=(0, 32, 33) logical=(0, 33, 3)
    Partition 1 has different physical/logical endings:
         phys=(980, 21, 1) logical=(1015, 201, 62)
    Partition 1 does not end on cylinder boundary
    /dev/sdb2   *        1016        1022       40960   b Win95 FAT32
    Partition 2 has different physical/logical beginnings (non-Linux?):
         phys=(980, 21, 2) logical=(1015, 202, 1)
    Partition 2 has different physical/logical endings:
         phys=(985, 46, 21) logical=(1021, 23, 18)
    Partition 2 does not end on cylinder boundary

    And, when I insert this flash, I see sdb1 mounted in the PCManFM.

    Next, my internal HD. Here "fdisk -l":
    

    Disk /dev/sda: 160.0 GB, 160041885696 bytes
    255 heads, 63 sectors/track, 19457 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    
       Device Boot      Start         End      Blocks  Id System
    /dev/sda1               1         637     5116671  12 Compaq diagnostics
    /dev/sda2   *         638       18021   139636980   7 HPFS/NTFS
    /dev/sda3           18022       19457    11534639+  f Win95 Ext'd (LBA)
    /dev/sda5           18022       18152     1050624  83 Linux
    /dev/sda6           18153       19062     7307264  83 Linux
    /dev/sda7           19062       19457     3173679+ 83 Linux

    And here is my /etc/fstab:
    

    # /etc/fstab: Information about static filesystems.
    #
    proc          /proc        proc     defaults             0       0
    sysfs         /sys         sysfs    defaults             0       0
    devpts        /dev/pts     devpts   rw,gid=5,mode=0620   0       0
    tmpfs         /dev/shm     tmpfs    defaults             0       0
    #/dev/cdrom    /media/cdrom iso9660  user,ro,noauto       0       0
    #/dev/sda3     /home        ext3     defaults             0       2
    #/dev/hdb1     /mnt/data    btrfs    defaults             0       2
    #datasvr:/nfs/home  /home   nfs      tcp,nolock           0       0
    #/dev/sda5	swap	swap	defaults	0 0
    /dev/sda6	/mnt/slitaz	ext3	defaults	0 0
    /dev/sda2	/mnt/acer	ntfs-3g	defaults	0 0

    I can't see already mounted partitions (sda2, sda6) on the left PCManFM panel.

    And, of course, I have no CD-ROM on my notebook, so problem with eject not touched me.

    (Auto)mounting via pcmanfm works just after something like addgroup tux disk
    I did this in TazPanel - Settings groups gui. But only in deleted on server last rolling. I'm glad it's saved by me.
    In 5.0rc1 all of this is broken.
