The relevant init scripts were updated so as to automatically share
ZFS datasets using "zfs share -a" at boot time.

* Update paths to zpool/zfs tools,
* Log less for non-error conditions,
* Don't be fatal if umount fails at shutdown -- final init remount
will take care of it if /usr or / are in use

These days most disk drivers will probe for devices asynchronously.
This means it's possible that when you zfs init script runs all the
required block devices may not yet have been discovered. The result
is the pool may fail to cleanly import at boot time. This is
particularly common when you have a large number of devices.
The fix is for the init script to block until udev settles and we
are no longer detecting new devices. Once the system has settled
the zfs modules can be loaded and the pool with be automatically
imported.
To support automatically mounting your zfs on filesystem on boot
a basic init script is needed. Unfortunately, every distribution
has their own idea of the _right_ way to do things. Rather than
write one very complicated portable init script, which would be
invariably replaced by the distributions own anyway. I have
instead added support to provide multiple distribution specific
init scripts.
The correct init script for your distribution will be selected
by ZFS_AC_DEFAULT_PACKAGE which will set DEFAULT_INIT_SCRIPT.
During 'make install' the correct script for your system will
be installed from zfs/etc/init.d/zfs.DEFAULT_INIT_SCRIPT to the
usual /etc/init.d/zfs location.
Currently, there is zfs.fedora and a more generic zfs.lsb init
script. Hopefully, the distribution maintainers who know best
how they want their init scripts to function will feedback their
approved versions to be included in the project.
This change does not consider upstart jobs but I'm not at all
opposed to add that sort of thing.
