#		initialized for one of the "multi user" run levels (i.e.
#		levels 1 through 6).  It usually does mounting of file

# Slackware-Mini-Quota-HOWTO:
# To really activate quotas, you'll need to add 'usrquota' and/or 'grpquota' to
# the appropriate partitions as listed in /etc/fstab.  Here's an example:
#
# /dev/hda2      /home      ext3     defaults,usrquota      1   1
#
# You'll then need to setup initial quota files at the top of the partitions
# to support quota, like this:
# touch /home/aquota.user /home/aquota.group
# chmod 600 /home/aquota.user /home/aquota.group
#
# Then, reboot to activate the system.
# To edit user quotas, use 'edquota'.  See 'man edquota'.  Also, the
# official Quota Mini-HOWTO has lots of useful information.  That can be found
# here:  /usr/doc/Linux-HOWTOs/Quota

# Check quotas and then turn quota system on:
if grep -q quota /etc/fstab ; then
