I noticed that Neil Brown wrote some patches fairly early on in the 2.4
cycle to do tree-based quota by UID. The last patch-set I found was
against 2.4.14
(http://cgi.cse.unsw.edu.au/~neilb/patches/linux/2.4.14/) from late
2001, and did not come with patches to quota-tools.
Following is my tree-quota patch updated to 2.6.14.3. However it
doesn't do exactly what you claim to want.
Thanks.
You still need to assign a uid to each user (the kernel needs some
number to use as an index into the quotas file). But only the top-level
directory of each tree needs to be owned by the uid. Files beneath the
top can be owned by anyone.
I'm hoping to modify your patch to use the inode at the root of the tree
instead of a particular uid as the quota owner, so that setting a quota of
50Mb on /some/location would charge usage for any children of
/some/location to the inode of /some/location.
I can dig-up a patch for quota-utils if you want to proceed with this.
I would appreciate that.
