  TITLE:		Quota Support
  LFS VERSION:	3.3 + (maybe all)
  AUTHOR:		Remco Jansen <remcorkz at xs4all.nl>
  
  SYNOPSIS:
  	This hint describes how to setup quota support on your LFS system.
  
  HINT:
  
  Wrote this hint because there's one little thing that you may come across trying
   to setup quota-tools. Normally on an LFS system the mtab file is created as a
  symlink to /proc/mounts. The quota-tools programs won't work with this
  configuration.
  
  First make sure quota support is built into your kernel. If not, recompile your 
  kernel.
  
  Also you need to get the quota-tools package from
  http://prdownloads.sourceforge.net/linuxquota/quota-3.08.tar.gz?download
  (at the time of this writing version is 3.08).
  Their homepage is can be found at http://sourceforge.net/projects/linuxquota/.
  
  
  Install the quota-tools package as normally.
  
  ./configure
  
  
  Edit the Makefile by hand to setup the directories so that they obey the LFS
  standard. (prefix=/bin, sysconfdir=/etc)
  
  make && make install
  
  
  Now the tools are installed properly, you have to change the /etc/mtab symlink
  to the more-used /etc/mtab file.
  (see http://archive.linuxfromscratch.org/mail-archives/lfs-dev/2002/08/0387.html
  for more information on this issue)
  
  rm -f /etc/mtab &&
  touch /etc/mtab &&
  chmod 644 /etc/mtab
  
  
  In order to let the mtab file be accurate (also when the system has crashed for 
  some reason) we add an mtab initialization part to the mountfs initscript.
  
  Add the following lines to the start)-section of the mountfs initscript, right 
  after the remounting of the root file system in read-write mode lines.
  
                  # Because we have replaced the /etc/mtab-symlink by a file
                  # we have to update the status of /etc/mtab.
                  # First remove it. Then add an entry for the already
                  # mounted root file system to it.
  
                  echo "Clearing /etc/mtab..."
                  : > /etc/mtab
                  evaluate_retval
                  echo "Update mtab file with root file system..."
                  mount -f -o remount /
                  evaluate_retval
                  echo "Update mtab file with proc file system..."
                  mount -f /proc
                  evaluate_retval
  
  
  Create the quota initscript as follows:
  
  #!/bin/bash
  # Begin $rc_base/init.d/quotas
  
  # Based on sysklogd script from LFS-3.1 and earlier.
  # Rewritten by Gerard Beekmans  - gerard at linuxfromscratch.org
  
  source /etc/sysconfig/rc
  source $rc_functions
  
  case "$1" in
          start)
                  echo "Checking quotas on all filesystems..."
                  /usr/sbin/quotacheck -augM
                  evaluate_retval
                  echo "Turning quota administration on..."
                  /usr/sbin/quotaon -aug
                  evaluate_retval
                  ;;
  
          stop)
                  echo "Turning off quota administration..."
                  /usr/sbin/quotaoff -aug
                  evaluate_retval
                  ;;
  
          restart)
                  echo "Restarting quota administration not allowed."
                  ;;
  
          *)
                  echo "Usage: $0 {start|stop|reload|restart|status}"
                  exit 1
                  ;;
  esac
  
  # End $rc_base/init.d/quotas
  
  
  The last step is editing your /etc/fstab.
  
  For each filesystem on which you want to enable quota support add either
  usrquota or grpquota or the two of them to the options section of that file-
  system. (for this information you can also have a look at one of the thousands
  of quota how-to's)
  
  Reboot your system. (You may also update the mtab file by issueing the
  mount -f filesystem command for each already mounted filesystem, remount the 
  filesystems on which you're installing quota support and then start quota 
  administration by running quotaon -aug. However it is better to run the 
  quotacheck tool as well... So if possible: reboot.)
  
  The quotaon program will create the quota.user and/or quota.group files for each
  desired filesystem automatically.
  
  You're finished. Good luck.
