USB booting :: Storing files on USB



Quote (Juanito @ April 10 2008,11:51)
The current "install to usb" menu in dsl makes two partitions as stated previously, but you can manually make a single fat/fat32 partition and boot using syslinux or a single ext2 partition and boot using extlinux and no doubt (I haven't tried) you could also use grub to boot either of these partitions.

Thanks, Juanito.

I'm afraid I didn't quite explain properly--I already have a single (1 GiB, FAT32) partition on my USB stick, with dsl-embedded booting from it. What I would like to do is to give (i.e. chown) a folder within the memory stick (mounted as /cdrom) to user dsl (i.e. the default user in dsl), so that I can write to it without becoming root. When I try this within dsl, it says that I do not have permission, even if I try to do it as root.

That's probably mounted as RO.  Check `mount`

What's your boot parameters?  You could try adding the "frugal" cheatcode or maybe remounting the partition as RW.
This allows me to boot dsl from a 1GB usb stick formatted as a single ext2 partition:

Not being a windows guy, does fat32 even support multiple permissions? Isn't that why there is/was UMSDOS and UVFAT?

If your requirement dictates a single partiton then I would suggest to use Juanito's method.
Sorry I've not replied for a while--been busy with one thing and another.

It is possible to write to the mount--I can do so as superuser, and I have verified that the data is still there. I would essentially like to be able to do the same thing without logging in as root.

My preference is to make use of /cdrom, as I know it's consistent (regardless of how dsl is booted or on what system), and it's already formatted correctly for my purposes. If that's impossible, then fair enough...but I can't logically see why it would be impossible.
