Hi
I installed slitaz on usb dongle btrfs formated. Installation went fine, I modify fstab and menu.list as require to allow grub to boot. Unfortunately, grub seem to be unable to recognize the file system (error 17). I tried to solve the problem by chrooting and reinstalling grub (grub-install) without success. grub-install give me a "Could not find device for /boot: Not found or not a block device." message.
As installing slitaz on the same usb dongle ext4 formated worked very well, I can say btrfs is the problem.
Please, Is it possible to use a slitaz on a btrfs file system?
(sorry for my bad english)

Did you manually install grub2 that supports btrfs to the flash drive?
I doubt the boot loader grub4dos on the slitaz live iso's supports btrfs.

Hi mojo, thank you
You're right, grub2 is the solution. Maybe the procedure would be helpfull to others :
1. boot a live slitaz rolling, install slitaz on my btrfs formated flash drive without a boot loader (grub4dos)
2. mount my btrfs flash drive : # mount -o subvol=/,subvolid=5 /dev/sdb1 /mnt
3. copy over the DNS details to use an internet in the chroot environment :
# cp /etc/resolv.conf /mnt/etc/resolv.conf
4. mount everything needed by a chroot environment :
# for i in dev dev/pts sys proc run; do sudo mount --bind /$i mnt/$i; done
5. chroot in my flash drive : # chroot /mnt and test internet # ping www.google.com
6. recharge slitaz database : # tazpkg recharge
7. get grub2 from slitaz : # tazpkg -gi grub2
8. install grub2 on the flash drive : # grub-mkconfig -o boot/grub/grub.cfg and # grub-install /dev/sdb
9. install btrfs in my chroot environment : # tazpkg -gi btrfs-libs btrfs-progs btrfs-mkfs
10. add a line in fstab : UUID=blablabla / btrfs ssd,noatime,compress=lzo,space_cache 0 1 too avoid kernel panic trying to find a root

Sorry, I made mistake in my last post. Please, would it be possible to delete it and consider this the error-free (hopefully) process description instead ?
Grub2 is the key to install and boot a slitaz rolling on a btrfs root filesystem. Hope the following procedure would be helpfull to you :
1. boot a live slitaz rolling, install slitaz on a btrfs formated flash drive without boot loader
2. don't reboot slitaz, instead mount the btrfs-formated flash drive :
# mount /dev/sdb1 /mnt
3. copy over the DNS details to use an internet in the chroot environment :
# cp /etc/resolv.conf /mnt/etc/resolv.conf
4. mount everything needed by a chroot environment :
# for i in dev dev/pts sys proc run; do mount --bind /$i mnt/$i; done
5. chroot in btrfs-formated flash drive :
# chroot /mnt
then test internet :
# ping http://www.google.com
6. If everything is OK, you can recharge slitaz database :
# tazpkg recharge
7. get and install grub2 from slitaz depots :
# tazpkg -gi grub2
8. install grub2 on the flash drive :
# grub-mkconfig -o boot/grub/grub.cfg
# grub-install /dev/sdb
9. install btrfs in the chroot environment :
# tazpkg -gi btrfs-libs btrfs-progs btrfs-mkfs
10. add the following line in fstab of your chrooted environment :
UUID=blablabla / btrfs rw,relatime,compress=lzo,space_cache 0 1
# nano /etc/fstab
11. in /etc/boot/grub.conf, change each occurence of hd1 to hd0 and each occurence of sdb1 to sda1
# nano /etc/boot/grub.cfg
12. you can now boot your brand new slitaz on a btrfs-formated flash drive :-)

Hi sorry for ressurection..
7 years after, now new rolling version (2026-3) has GRUB2 installed, and it automagically detects the internet so you can skip to step 8.
However, at step 8,
$ grub-mkconfig -o boot/grub/grub.cfg ;
Command gives the line:
$ /usr/sbin/grub-probe: error: failed to get canonical path of 'tmpfs'.
I don't know what am i doing wrong (yet)
Feel free to help if you read this, any help is highly appreciated.
