Problem with USB Stick installation

[termiflyer]

I've followed the simple instructions here (it won't let me post the URL ... the howto on the wiki about making a USB stick w/ BT3) (thank you to author!) and my BackTrack 3 works great.

My problem is that my changes don't seem to stick: simple example is my desktop wallpaper in BT3 changes back to default; another example is I installed the source for a newer linux kernel (as detailed in an aircrack tutorial to get my iwl4965 working) to /usr/src/linux and next time I started it up it's gone. Needless to say I need to figure it out because I need to configure my wireless manually as it is to get it to work at all.

When I select BackTrack with Persistent Changes during login and make no modifications, it boots but obviously doesn't work. When I edit the command and point changes to /dev/sda, it boots but doesn't stick. When I boot my USB shows up as /dev/sdb1, so I assume that is what I need ... but when I point changes to there, it won't boot at all. I'm in Windows now so I can't get the exact message right now (i will later), but boot stops when it tries to use /dev/sdb1 for something.

Thanks

Not sure if this helps but have you tried this from the wiki?

After having produced the personalization, open the console and digit dir2lzm /mnt/live/memory/changes changes.lzm (changes.lzm or pippo.lzm ...) changes.lzm you have in root folder, paste in USB modules folder (BT/modules). Reboot you have saved setting up. -bzImage

found under Howto#Save_configuration_to_USB_stick, generally works pretty well for me, if understand what you're trying to accomplish.

I'll try that out ... thanks!

Here's what happens when I choose BT3 w/ persistent changes and then edit the command w/ /dev/sdb1 as the howto says:

using BT3 data from /mnt/sdb1/BT3
setting up directory for changes
/dev/sdb1
testing the filesystem for posix compatibility
not compatible - starting posixovl
setup union directory (using aufs, with udba=none)
mount: mounting aufs on union failed
Fatal error occured - can't setup union (aufs)
Something went wrong and we can't continue. This should never happen.
Please reboot using Ctl-Alt-Delete

I'm going to try the above suggestion now.
