I would like to be able to apply a quota to a particular tree, and have every file and directory in the path of that tree count toward that tree's quota usage. I can prevent hard links across trees.
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 22.214.171.124. However it doesn't do exactly what you claim to want.
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 can dig-up a patch for quota-utils if you want to proceed with this.
