I have made some space available on a NetBSD/i386 machine via Samba 1.9.18
to the windows machines on my network.  To ensure that these users don't
fill the partition (and break something), I put them all in a group called
users and gave that group a quota.  However, I cannot set the group quota to
anything larger than 4 Gig.

Is there a limit on user/group quotas to 4 Gig?

Thanks!   Mike.
