:his $HOME on the /home PFS and thus blow the fs up, or?  Correct me if
:I'm wrong.  If I'm right what is the policy for admins using HAMMER on a
:machine with a lot of user shells?

:PS: Someone interested to hack quota support for HAMMER? :)

    Basically we would need a quota system in the kernel layer that
    works for all filesystems, rather then the current VFS-specific
    quota system.
