Ok, downloaded vl5.8 std live iso, burned it to disk then copied to my usb drive.
ran syslinux and renamed the isolinux.cfg to syslinux.cfg system now boots!
ok, so now I want to make changes and same so they are there next time I boot.
for example I want to edit /etc/hosts and have those changes there the next time I boot off the USB drive.
I don't want to do a regular install ( I think) because I might use the USB drive to boot another machine so I need the live version so it will scan and set up all the hardware.
Any help would be great!
thanks!

good to hear your up and running with it.
you need to find out which device name your usb drive gets when the system boots i.e. /dev/sda1
then you add this "changes=/dev/sda1" to your boot line in syslinux.cfg (changing /dev/sda1 to match your device of course)
let us know if that works for you,

hmm, I'm doing something wrong.
root:# mount
tmpfs on / type tmpfs (rw)
/dev/sda1 on /mnt/sda1 type vfat (rw)
/dev/sda2 on /mnt/sda2 type ntfs (ro)
usbfs on /proc/bus/usb type usbfs (rw,devgid=10,devmode=0666)
/dev/sdb1 on /mnt/vl-hot/sdb/vol1 type vfat (rw,noexec,nosuid,nodev,noatime,uid=0,gid=100,fmask=0111,dmask=0000,quiet,codepage=437,iocharset=iso8859-15)
/dev/sdb1 on /mnt/sdb1_removable type vfat (rw)
now if I do ls on /mnt/sda1 I get :
root:# ls /mnt/sda1

I'm not sure what I'm looking for but my syslinux.cfg has the "changes=" line as the last line.
I tried "changes=/dev/sda1" and "changes=/dev/sdb1" but neither seem to make changes stick.
my test case is to edit /etc/hosts and see if changes are there on reboot.
root:# cat syslinux.cfg
display boot/splash.cfg

it needs to be in your append line, like this append vga=788 splash=silent max_loop=255 initrd=boot/initrd init=linuxrc load_ramdisk=1 prompt_ramdisk=0 ramdisk_size=10000 root=/dev/ram0 changes=/dev/sdb1 rw |

ok, added the "changes=/dev/sdb1" to the append line, rebooted edited /etc/hosts but once I rebooted again, the changes were gone.
display boot/splash.cfg

From my experience in slax 6, changes=/dev/sdb1 means to save changes in the partition found in /dev/sdb1 (usually ext2) which is probably not what you want to do. I am not sure but check if there is a command called 'mkchanges' and try using that to make a save file somewhere. Then in your syslinux.cfg make changes=<relative path from root of drive to save file>. Well, that's how it's done is Slax 6 which uses the linux-live 6 scripts, so I'm not sure if it also applies to linux-live 5(the one used in VL-5.8 live. Edit: I inspected the VL-5.8 live cd and turns out there wasn't anything to make a filesystem. So based off some stuff in slax, here is what you do to keep changes. cd <path to flashdrive>
touch save.dat #filename of choice
dd if=/dev/zero of=save.dat bs=1 seek=<size in mb>M count=0
mkfs.xfs save.dat
Then, in your syslinux.cfg put "changes=save.dat" Note: I used xfs because that's what slax uses and you can optionally grow the fs, but you can use other filesystems as well, as long as it's supported, I think. You should give about 256mb for the changes file, which is usually more than enough. |

ok cded to /mnt/sdb1_removable
created file save.dat
-rwxr-xr-x 1 root root 209715200 2007-08-20 15:34 save.dat
dd if=/dev/zero of=save.dat bs=1 seek=200M count=0
mkfs.xfs save.dat
ran with no errors.
then added the changes=save.dat to the append line of the linux label
append vga=788 splash=silent max_loop=255 initrd=boot/initrd init=linuxrc load_ramdisk=1 prompt_ramdisk=0 ramdisk_size=10000 root=/dev/ram0 changes=save.dat rw
rebooted, edited /etc/hosts and saved. Rebooted and changes still not there.

ok so that didnt work.
wiped out my usb drive, created 2 partitions : 1 fat16 and 1 ext2
rebuilt the livecd into the fat16 reran syslinux and booted.
created a file called saved.cow in the ext2 file system
set "changes=saved.cow" in the syslinux.cfg
rebooted and still not working. is the "changes" option correct?

the changes= boot option has worked for me.
All the documentation I have found, (and the way it worked for me) says that the changes option should be used with the device name.
I have read that if a file called save.dat is found on the device used in the changes= option that it will be used but that it is not required.
there should also be a folder called rootcopy on the usb that can be used to copy files into the root file system on boot like /etc/hosts

Did you try using ext2 for the save.dat file? But since you already have an ext2 partition, you can just use that to save changes to.

I also needed to save my settings for Vector Live on a UFD. Maybe look at this thread?: http://www.vectorlinux.com/forum2/index.php?topic=3651.15 |

That works if you just want to change a single setting permanently, but it doesn't work if you want to save what you've done in a single session. |

uelsk8s,
can you please post your syslinux.cfg with this option working?
when you say device name you mean /dev/sbd1 example "changes=/dev/sbd1" and then on that device have a save.dat file ?

i just added it like this
label linux
kernel boot/vmlinuz
append vga=788 splash=silent max_loop=255 initrd=boot/initrd init=linuxrc load_ramdisk=1 prompt_ramdisk=0 ramdisk_size=10000 root=/dev/ram0 changes=/dev/sdb1 rw
and i did not make a save.dat file
you shouldnt need one if you use a linux filesystem

mine looks like yours
label linux
kernel boot/vmlinuz
append vga=788 splash=silent max_loop=255 initrd=boot/initrd init=linuxrc load_ramdisk=1 prompt_ramdisk=0 ramdisk_size=10000 root=/dev/ram0 changes=/dev/sdb2 rw
and my /dev/sdb2 is ext2 as you can see here. but ........
root:# mount
tmpfs on / type tmpfs (rw)
/dev/sda1 on /mnt/sda1 type vfat (rw)
/dev/sda2 on /mnt/sda2 type ntfs (ro)
usbfs on /proc/bus/usb type usbfs (rw,devgid=10,devmode=0666)
/dev/sdb1 on /mnt/vl-hot/sdb/vol1 type vfat (rw,noexec,nosuid,nodev,noatime,uid=0,gid=100,fmask=0111,dmask=0000,quiet,codepage=437,iocharset=iso8859-15)
/dev/sdb2 on /mnt/vl-hot/sdb/vol2 type ext2 (rw,noexec,nosuid,nodev,noatime)
/dev/sdb1 on /mnt/sdb1_removable type vfat (rw)
/dev/sdb2 on /mnt/sdb2_removable type ext2 (rw)
logged in as root. did a touch test.txt in / then rebooted and it was gone.
looking at dmesg I see the append line was read
Kernel command line: vga=788 splash=silent max_loop=255 initrd=boot/initrd init=linuxrc load_ramdisk=1 prompt_ramdisk=0 ramdisk_size=10000 root=/dev/ram0 changes=/dev/sdb2 rw BOOT_IMAGE=boot/vmlinuz
thoughts?
