User and group mount options for ext filesystemsUser and group mount options for ext filesystemsPosted May 17, 2012 6:00 UTC (Thu) by geofft (subscriber, #59789)In reply to: User and group mount options for ext filesystems by pr1268 Parent article: User and group mount options for ext filesystems
From the next line in the article:
"which would make the files appear to be owned by m.x and would create new files as n.y."
The usefulness of this makes is more obvious when you realize that m and x are user-visible uids/gids, and n and y are on-disk uids/gids -- different namespaces entirely. That is, if user geofft on my current system is uid 1001, and I'm mounting my laptop's root partition where user geofft is 1000, then I should mount with uid=1001:1000 so that everything appears owned by me now, but also so that anything new remains owned by me when I put the disk back into my laptop. 1001 is from the host's /etc/passwd, 1000 from the target's.
