   1 DESCRIPTION
   2   These script were written with the primary intention of being portable and
   3   usable on as many systems as possible.
   4
   5   This is, in practice, usually not possible. But the intention is there.
   6   And it is a good one.
   7
   8   They have been tested successfully on:
   9
  10     * Debian GNU/Linux Bookworm
  11     * Gentoo
  12
  13 SUPPORT
  14   If you find that they don't work for your platform, please report this
  15   at the OpenZFS issue tracker at https://github.com/openzfs/zfs/issues.
  16
  17   Please include:
  18
  19     * Distribution name
  20     * Distribution version
  21     * Where to find an install CD image
  22     * Architecture
  23
  24   If you have code to share that fixes the problem, that is much better.
  25   But please remember to try your best keep portability in mind. If you
  26   suspect that what you're writing/modifying won't work on anything else
  27   than your distribution, please make sure to put that code in appropriate
  28   if/else/fi code.
  29
  30   It currently MUST be bash (or fully compatible) for this to work.
  31
  32   If you're making your own distribution and you want the scripts to
  33   work on that, the biggest problem you'll (probably) have is the part
  34   at the beginning of the "zfs-functions" file which sets up the
  35   logging output.
  36
  37 INSTALLING INIT SCRIPT LINKS
  38   To setup the init script links in /etc/rc?.d manually on a Debian GNU/Linux
  39   (or derived) system, run the following commands (the order is important!):
  40
  41     update-rc.d zfs-import   start 07 S .       stop 07 0 1 6 .
  42     update-rc.d zfs-load-key start 02 2 3 4 5 . stop 06 0 1 6 .
  43     update-rc.d zfs-mount    start 02 S       . stop 06 0 1 6 .
  44     update-rc.d zfs-zed      start 07 2 3 4 5 . stop 08 0 1 6 .
  45     update-rc.d zfs-share    start 27 2 3 4 5 . stop 05 0 1 6 .
  46
  47   To do the same on RedHat, Fedora and/or CentOS:
  48
  49     chkconfig zfs-import
  50     chkconfig zfs-load-key
  51     chkconfig zfs-mount
  52     chkconfig zfs-zed
  53     chkconfig zfs-share
  54
  55   On Gentoo:
  56
  57     rc-update add zfs-import boot
  58     rc-update add zfs-load-key boot
  59     rc-update add zfs-mount boot
  60     rc-update add zfs-zed default
  61     rc-update add zfs-share default
  62
  63   The idea here is to make sure all of the ZFS filesystems, including possibly
  64   separate datasets like /var, are mounted before anything else is started.
  65
  66   Then, ZED, which depends on /var, can be started.  It will consume and act
  67   on events that occurred before it started.  ZED may also play a role in
  68   sharing filesystems in the future, so it is important to start before the
  69   'share' service.
  70
  71   Finally, we share filesystems configured with the share\* property.
