* Fix regression - "OVERLAY_MOUNTS" should have been "DO_OVERLAY_MOUNTS".
* Fix update-rc.d commands in postinst. Thanx to subzero79@GitHub.
* Fix make sure a filesystem exists before trying to mount in mount_fs()
* Fix local variable usage.
* Fix to read_mtab():
* Strip control characters (space - \040) from /proc/mounts GLOBALY,
not just first occurrence.
* Don't replace unprintable characters ([/-. ]) for use in the variable
name with underscore. No need, just remove them all together.
* Add check_boolean() to check if a user configure option is
set ('yes', 'Yes', 'YES' or any combination there of) OR '1'.
Anything else is considered 'unset'.
* Add a ZFS_POOL_IMPORT to the default config.
* This is a semi colon separated list of pools to import ONLY.
* This is intended for systems which have _a lot_ of pools (from
a SAN for example) and it would be to many to put in the
ZFS_POOL_EXCEPTIONS variable..
* Add a config option "ZPOOL_IMPORT_OPTS" for adding additional options
to "zpool import".
* Add documentation and the chance of overriding the ZPOOL_CACHE
variable in the config file.
* Remove "sort" from find_pools() and setup_snapshot_booting().
Sometimes not available, and not really necessary.

Closes#3747
This is some minor fixes to commits 2cac7f5f11
and 2a34db1bdb.
* Make sure to alien'ate the new initramfs rpm package as well!
The rpm package is build correctly, but alien isn't run on it to
create the deb.
* Before copying file from COPY_FILE_LIST, make sure the DESTDIR/dir exists.
* Include /lib/udev/vdev_id file in the initrd.
* Because the initrd needs to use '/sbin/modprobe' instead of 'modprobe',
we need to use this in load_module() as well.
* Make sure that load_module() can be used more globaly, instead of
calling '/sbin/modprobe' all over the place.
* Make sure that check_module_loaded() have a parameter - module to
check.

Closes#3626
* In read_mtab(), fix problems (!?) in the mounts file. It will record
'rpool 1' as 'rpool\0401' instead of 'rpool\00401' which seems to be the
correct (at least as far as 'printf' is concerned). Use this using the
external 'echo' command (and not the one built in to the shell) because
the internal one would interpret the backslash code (incorrectly), giving
us a instead.
* Remove reregister_mounts() - no longer needed.
* For Gentoo, the zfs_log_failure_msg() should use eend(), not eerror()
(which requires an error message, which we don't have).

This reverts commit 036391c980.
Because #3509 came just after this commit was accepted and is related
to the original problem the commit was supposed to fix, we need to
solve the problem in another way.

Use the 'mount' command instead of /proc/mounts to get a list of matching
filesystems.
This because /proc/mounts reports a pool with a space 'rpool 1' as
'rpool\0401'. The space is encoded as 3-digit octal which is legal.
However 'printf "%b"', which we use to filter out other illegal
characters (such as slash, space etc) can't properly interpret this
because it expects 4-digit octal. We get a instead of the space
we expected. The correct value should have been 'rpool\00401' (note
the additional leading zero).
So use 'mount', which interprets all backslash-escapes correctly,
instead.

* Change the order of the function library check/load.
Redhat based system _can_ have a /lib/lsb/init-functions file (from
the redhat-lsb-core package), but it's only partially what we can use.
Instead, look for that file last, giving the script a chance to catch
the 'real' distribution file.
* Filter out dashes and dots in dataset name in read_mtab().
* Get rid of 'awk' entirely. This is usually in /usr, which might not
be availible.
* Get rid of the 'find /dev/disk/by-*' (find is on /usr, which might not
be availible). Instead use echo in a for loop.
* Rebuild scripts if any of the *.in files changed.
* Move the sed part that filters out duplicates inside the check fo
valid variable.

* Based on the init scripts included with Debian GNU/Linux, then take code
from the already existing ones, trying to merge them into one set of
scripts that will work for 'everyone' for better maintainability.
* Add configurable variables to control the workings of the init scripts:
* ZFS_INITRD_PRE_MOUNTROOT_SLEEP
Set a sleep time before we load the module (used primarily by initrd
scripts to allow for slower media (such as USB devices etc) to be
availible before we load the zfs module).
* ZFS_INITRD_POST_MODPROBE_SLEEP
Set a timed sleep in the initrd to after the load of the zfs module.
* ZFS_INITRD_ADDITIONAL_DATASETS
To allow for mounting additional datasets in the initrd. Primarily used
in initrd scripts to allow for when filesystem needed to boot (such as
/usr, /opt, /var etc) isn't directly under the root dataset.
* ZFS_POOL_EXCEPTIONS
Exclude pools from being imported (in the initrd and/or init scripts).
* ZFS_DKMS_ENABLE_DEBUG, ZFS_DKMS_ENABLE_DEBUG_DMU_TX, ZFS_DKMS_DISABLE_STRIP
Set to control how dkms should build the dkms packages.
* ZPOOL_IMPORT_PATH
Set path(s) where "zpool import" should import pools from.
This was previously the job of "USE_DISK_BY_ID" (which is still used
for backwards compatibility) but was renamed to allow for better
control of import path(s).
* If old USE_DISK_BY_ID is set, but not new ZPOOL_IMPORT_PATH, then we
set ZPOOL_IMPORT_PATH to sane defaults just to be on the safe side.
* ZED_ARGS
To allow for local options to zed without having to change the init script.
* The import function, do_import(), imports pools by name instead of '-a'
for better control of pools to import and from where.
* If USE_DISK_BY_ID is set (for backwards compatibility), but isn't 'yes'
then ignore it.
* If pool(s) isn't found with a simple "zpool import" (seen it happen),
try looking for them in /dev/disk/by-id (if it exists). Any duplicates
(pools found with both commands) is filtered out.
* IF we have found extra pool(s) this way, we must force USE_DISK_BY_ID
so that the first, simple "zpool import $pool" is able to find it.
* Fallback on importing the pool using the cache file (if it exists) only
if 'simple' import (either with ZPOOL_IMPORT_PATH or the 'built in'
defaults) didn't work.
* The export function, do_export(), will export all pools imported, EXCEPT
the root pool (if there is one).
* ZED script from the Debian GNU/Linux packages added.
* Refreshed ZED init script from behlendorf@5e7a660 to be portable so it
may be used on both LSB and Redhat style systems.
* If there is no pool(s) imported and zed successfully shut down, we will
unload the zfs modules.
* The function library file for the ZoL init script is installed as
/etc/init.d/zfs-functions.
* The four init scripts, the /etc/{defaults,sysconfig,conf.d}/zfs config file
as well as the common function library is tagged as '%config(noreplace)' in
the rpm rules file to make sure they are not replaced automatically if locally
modifed.
* Pitfals and workarounds:
* If we're running from init, remove stale /etc/dfs/sharetab before importing
pools in the zfs-import init script.
* On Debian GNU/Linux, there's a 'sendsigs' script that will kill basically
everything quite early in the shutdown phase and zed is/should be stopped
much later than that. We don't want zed to be among the ones killed, so add
the zed pid to list of pids for 'sendsigs' to ignore.
* CentOS uses echo_success() and echo_failure() to print out status of
command. These in turn uses "echo -n \0xx[etc]" to move cursor and choose
colour etc. This doesn't work with the modified IFS variable we need to
use in zfs-import for some reason, so work around that when we define
zfs_log_{end,failure}_msg() for RedHat and derivative distributions.
* All scripts passes ShellCheck (with one false positive in do_mount()).
