I have Damn Small Linux installed on my 2GB Kingston datatraveler flash drive. I boot it from the drive and once on DSL I am unable to mount the flash drive, and cant figure out how to back up and save my settings to it. Is there a way to mount the flash drive or use it to keep my settings so next time I boot from it everythings the same. Or is there no way to mount the flash drive that DSL is booted from on DSL?

well, DSL mounts the usb drive, as cdrom or /cdrom

it should say, issuing "mount" in terminal
/dev/sda1 /cdrom

now, DSL must have a different partition to save to besides the one it boots from
you must make your USB 2 partitions

sda1 fat32
sda2 ext2

your usb may be sdb1, sdf1, etc
but DSL will usually recognize it as sda

you also gotta edit the syslinux.cfg on usb and tell DSL
where to save settings to

example
restore=sda2 mydsl=sda2

just put that code in syslinux.cfg entry(s)

I don't know much about DSL, but the more recent 'buntu "live CD" distros offer the option to install to a USB drive, that'll boot if your PC has the ability to boot from a USB drive (check your BIOS).

I just tried a kubuntu 9.10 live CD (I did not like it) but the offer was there, along with the option to offer space to save "home" and configuration files for the next reboot from a USB drive.

You might want more than 2GB on the drive. They are cheap now.
