USB booting :: Persistence on usb



Hi,

i have successfully installed a dsl on an usb pen (Two partitions FAT 800 MB and EXT2 1200MB).

My second step is to install jre 1.5 and on every boot (without entering dsl home=sdb2) load the paths and launch my java app automatically.  

My problem is, I try to install jre as a mydsl extension on the second partition (sda2) everything went ok. But even if i follow the steps described at the persistence wiki-chapter nothing is restored on the next boot!  When I select on booting 'F2, then dsl home=/dev/sda2' the XServer doesnt starts!

Could someone describe the necessary steps for a beginner?  

After a long time struggle with this Im really distressed.

Thanks, kemal

try home=sda2 (follow by example)
tried also, doesnt help. Is it reliable that I could use an usb partition? what can ensure the name sda2 ? Must I every time enter the home=sdxxx ?
If you use a whole partition, make sure it is formatted (ext2) and empty.  Yes, you can enter it every time you want to use it like that.
Its already formated (ext2) and empty. Even the created folders disappear after reboot. May I made something essential wrong as a newbie.
