I'm not sure if update-rc.d with insserv is still supported (still running
Wheezy),
but here goes:
I'm the maintainer for ZFS On Linux FOR ZFS On Linux (I'm making the packages
for
ZoL provided in the ZoL archives - hopefully I can provide some help to get it
in Debian GNU/Linux now that it seems the lawyers have come back with
"something").
But I can't get the boot (or rather shutdown/reboot) order correctly!
These are the LSB headers in the files:
* zfs-import
### BEGIN INIT INFO
# Provides: zfs-import zpool
# Required-Start: $local_fs zfs-zed
# Required-Stop: $local_fs
# Default-Start: S

### END INIT INFO

### BEGIN INIT INFO

samba4 zfs-mount
# Short-Description: Network share ZFS datasets and volumes.

# Description: zed monitors ZFS events. When a zevent is posted,

### END INIT INFO
My INTENTION is to have them started in this order:
1. zfs-zed
2. zfs-import
3. zfs-mount
4. zfs-share
and stopped in the reverse order. I create the links with update-rc.d like this:
update-rc.d zfs-zed start 18 S . stop 08 0 1 6 .
update-rc.d zfs-import start 11 S . stop 07 0 1 6 .
update-rc.d zfs-mount start 02 2 3 4 5 . stop 06 0 1 6 .
update-rc.d zfs-share start 03 2 3 4 5 . stop 05 0 1 6 .
The boot up works fine, but not the stop/reboot. It stopped in this order
instead:
1. zfs-import
2. zfs-mount
3. zfs-share
4. zfs-zed
This is incorrect (zfs-import and zfs-share should change places). The K links
look ok (and works as intended if creating the /etc/init.d/.legacy-bootordering
file):
# find /etc/rc?.d/K* | sort | grep zfs
/etc/rc0.d/K01zfs-share
/etc/rc0.d/K02zfs-mount
/etc/rc0.d/K03zfs-import
/etc/rc0.d/K04zfs-zed
/etc/rc1.d/K01zfs-share
/etc/rc1.d/K02zfs-mount
/etc/rc1.d/K03zfs-import
/etc/rc1.d/K04zfs-zed
/etc/rc6.d/K01zfs-share
/etc/rc6.d/K02zfs-mount
/etc/rc6.d/K03zfs-import
/etc/rc6.d/K04zfs-zed
Even the /etc/init.d/.depend.stop looks ok (as far as I can read it):
TARGETS = urandom virtualbox-guest-utils zfs-share atd exim4 plymouth
sendsigs zfs-mount zfs-import rsyslog umountnfs.sh zfs-zed rpcbind nfs-common
hwclock.sh networking umountfs umountroot halt reboot
sendsigs: atd virtualbox-guest-utils plymouth exim4 zfs-share
rsyslog: atd sendsigs exim4
umountnfs.sh: atd virtualbox-guest-utils plymouth rsyslog exim4
sendsigs zfs-share
zfs-zed: zfs-import
rpcbind: umountnfs.sh
nfs-common: umountnfs.sh
hwclock.sh: atd rsyslog nfs-common
networking: rpcbind exim4 umountnfs.sh zfs-share
umountfs: atd virtualbox-guest-utils hwclock.sh zfs-mount plymouth
zfs-zed zfs-import rpcbind urandom networking exim4 umountnfs.sh zfs-share
umountroot: umountfs
halt: umountroot
reboot: umountroot
Yet it still insists on shutting down the services in the wrong order...
