### Network device support ###
# Most of these drivers will probe automatically for the card if you don't

# I/O.  For complete information, see the net-modules.txt file that comes
# with the Linux 2.2.x source code.  This file can also be found on the
# Slackware CD-ROM in the /docs/linux-2.2.x/ directory.
#
# First, if setup probing found a network card, there may be an 'rc.netdevice'
# file that we should run to load the network module:

  . /etc/rc.d/rc.netdevice

# *** THIS IS STILL LOADED BY DEFAULT ***
# SCSI emulation support.  This will provide SCSI host adapter emulation
# for IDE ATAPI devices, and will allow you to use a SCSI device driver
# instead of a native ATAPI driver.  This is useful if you have an ATAPI
# device for which no native driver has been written (for example, an ATAPI
# PD-CD or CD-RW drive); you can then use this emulation together with an
# appropriate SCSI device driver.  Note that this option does NOT allow you
# to attach SCSI devices to a box that doesn't have a SCSI host adapter
# installed.  Also, you'll need to exclude your CD-RW from being grabbed by
# the normal ATAPI driver by passing a flag to the kernel at boot time.
# If you're using LILO, add this:  append="hdc=ide-scsi"
# Replace "hdc" with the appropriate device name.

# even be mounted the .pid files can't be correctly written in /var/run and

# touch /home/quota.user /home/quota.group
# chmod 600 /home/quota.user /home/quota.group
# Then, reboot to activate the system.
