UID and different distros

Post by AnneW » Mon Jul 29, 2013 10:46

When dual-booting it is helpful to have access to files on "the other" distro, sometimes config files, more often user data. Some distros like Mageia number UIDs from 500 while others, including Sabayon, start at 1000.

I normally mount partitions in fstab. Is there some way to add an alias that allows anne(500) to be read by anne(1000)?

First thing that comes to my mind would be to re-create user in one system, so uids will match (you can specify uid via '-u' parameter to adduser).

Other option is to add 'uid=anne' to fstab, but as far as I know, this would change owner of _all_ files on the filesystem.

you should better use same id everywhere.
You choose one / user and change uid in /etc/passwd file and then change find . -uid XXXX -exec chown YYYY {} \; on others distro.

You could activate acls, so both UIDs get access to your mounts.

You would have to add "acl" to your mount options in /etc/fstab, and use setfacl to add a second user to the access list of each file and directory.
