Before I take the time to create a Guide, I'd like to here from others if a guide for making a bootable USB Build (Not Live) build just like a hard drive on a usb ext3 stick. Here is the basic process and it works for SliTaz Rolling (have not test process with current but, will if anyone is interested).
Make a SliTaz Bootable (Not Live) usb stick. Its basically porting the HDD install to be on a usb stick with a swap file too.
Process: Requires gparted; a grub2 booting hard drive parition GNU Linux; 1 new partition (ext3 format) for SliTaz installation. Need a USB stick of 2-16GB ext3 format
Note:
A. Record what device id (/dev/sdX) is being use by SliTaz partition after HDD Install)
B. Remove all GRUB Packages from SliTaz HDD Build partiton.
C. The HDD GRUB2 Partition must have enough freespace to save a *.img of your create SliTaz Build (the new ext3 partition you will create and custom build).
1. Install Slitaz to new ext3 hard drive partition but, do not install bootloader
2. Reboot to partition that boots with grub2 -> update-grub (Grub 2 will be used on usb)
3. unknown linux will be shown on grub2 bootloader menu --> select it.
4. Use TazPanel and set coreect Keyboard, and laungage as required. If key map will not change, use Menu Option: Applications --> Preferences --> Keyboard mapping --> Configure as required - apply. Install desired packages and rboot to GRUB2 Partiton
5. GRUB2 Partition --> Terminal --> gparted --> Shrink SliTaz partition all the way +1 MB
6. Terminal --> sudo dd /dev/sdX of=./slitaz-custom-build.img bs=1MB status=progress && sync # Where X is the device ID number of your SliTaz Custom Built HDD partition)
7. Creating ext3 Bootable GRUB2 USB stick:
a. Gparted --> Device --> Partition Table --> New Partion ext3 --> apply --> exit --> sync.
b. Terminal --> sudo grub-install /dev/sdX # USB device name
c. Remove USB from system --> Reinsert USB --> Terminal --> sudo fdisk -l --> record /dev/sdX (use this device name in d., e., f. and g. below)
d. Termnial --> sudo dd if=/dev/sdX of=./usb-part-table-bootsector.img bs=1MB count=100 && sync (Remove USB and reinsert it)
e. Terminal --> gparted /dev/sdX --> Unmount partition it will have an error --> Partition --> Check (It will expand to full partition use. At this point you can "optional" shrink partition and create a 2-3GB linux-swap partition) --> Apply --> Exit --> sync
f. Remove and reisert USB Stick --> terminal --> cd to directory with usb-part-table-bootsector.img file --> sudo dd if=./usb-part-table-bootsector.img of=/dev/sdX1 bs=1MB status=progress && sync
g. Terminal --> update-grub --> (OSproper must run, if not, enable it on GRUB boot partition.) you should see your USB device name: /dev/sdX --> Reboot to HDD GRUB Bootloader --> select unownn linux /dev/sdX (USB DRIVE) --> boot to USB.
h. Login (Same username and password as HDD installed SliTaz.
i. Terminal --> blkid (Record USB UUID for /dev/sdX1. ALso UUID for swap partition if you created it /dev/sdX2
j. Menu --> Applications --> System tools --> SliTaz Panel --> login as root --> Boot --> Summary --> Main configuration file rcS.conf (click -- VIEW BUTTON) -- Find CHECK_FS="UUID....NUMBER" (Make sure this number is correct as gound in i. above)
k. If linux-swap partition --> Terminal --> sudo nano /etc/fstab --> verify on line that contains swap swap it is preceeded by correct device name /dev/sdX2
l. SliTaz Panel --> Login as root --> Packages --> Summary --> Top Search input box --> grub --> Select all grub2 packages --> install
m. Terminal --> sudo grub-mkconfig -o /boot/grub/grub.cfg
n. Terminal --> sudo update-grub # you should see correct /dev/sdX for USB Drive)
o. Reboot to USB (Usually pressing F12 key on boot and select usb storage / drive)
DONE - If all goes well you will have a bootalbe USB of your custom HDD SliTaz partition.
NOTE !!!! This has been tested on SliTaz Rolling and if Grub1 is not completel removed from system, even though grub2 packages are installed --> USB may fail to book.
Feel free to try this method on a develoment machine - never on a daily driver. IF i get anyone who is interested I will greate a SliTaz Guide for submission after beta testing the above process several times on both SliTaz current & rolling.
