# Initialize PCMCIA devices:
#
# NOTE: This used to be started near the top of rc.S so that PCMCIA devices
# could be fsck'ed along with the other drives.  This had some unfortunate
# side effects, however, since root isn't yet read-write, and /var might not
# even be mounted the .pid files can't be correctly written in /var/run and
# the pcmcia system can't be correctly shut down.  If you want some PCMCIA
# partition to be mounted at boot (or when the card is inserted) then add
# the appropriate lines to /etc/pcmcia/scsi.opts.
#
# Note that the stuff in /etc/pcmcia/ is only for 2.4.x kernels using
# 16-bit PCMCIA cards (not 32-bit Cardbus cards!).  For example, with a
# wireless card you might need to set options in /etc/pcmcia OR in
# /etc/rc.d/rc.wireless.conf, or even in /etc/rc.d/rc.inet1.conf (with

# Slackware-Mini-Quota-HOWTO:

# 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
