ext3 usb stick for two users

[karlorium]

I`d like to synch a folder with unison on two computers with an ext3 formated usb stick. But the usernames and primery group names are in each case different. Is there a possebility that the ext3 partition on my usb stick takes automaticly the user and group names of the user who mounted it like with vfat?

As you may already know it is thought unadvisable to use ext3 with flash memory as the frequent writing to the journal might shorten its life.

How about $ man mount there is much stuff about gid and uid in there??

Thank you for your message, lugoteehalt.

Thats right, enabeling journaling functionality for flash media is not a god idea.

To use the different mount options mentioned in man mount the user will need appropiate /etc/fstab entries. But if the admin won`t give you these permissions one will need other solutions.

Maybe I should revise my first post:
What I`m looking for is a secure, proper and good supported file system especially for flash media wich controls the specialbits and gives some freedom in seting user and group identification. I.e. root should have the possibility to enable the functioning that all files takes the uid and primary gid of the user who mounted the partition.
