This reverts commit b861bf8ddff67703, because according to @mdorman [1] this
change rendered his NixOS systems unbootable, and we probably don't want that.
[1] b861bf8ddf (commitcomment-16058598)
Allow usage of list of strings instead of a comma-separated string
for filesystem options. Deprecate the comma-separated string style
with a warning message; convert this to a hard error after 16.09.
15.09 was just released, so this provides a deprecation period during
the 16.03 release.

It's not entirely clear why this happens, but sometimes /proc/1/exe
returns a bogus value, like
/ar3a3j6b9livhy5fcfv69izslhgk4gcz-systemd-217/lib/systemd/systemd. In
any case, we can just conservatively assume that we need to restart
systemd when this happens.
Fixes#10261.
Fixes references coming from the mdadm udev rules.
This addresses #12722 (mdadm udev rules have references to /usr/bin) but
still won't fix the warning, though (if we want to fix the warnings, we
will have to patch the udev rules generater in services/hardware/udev).
For common mdraid functionality, this shouldn't fix anything, because
the wrong references seem to only apply to containers, see these
(wrapped) lines from ${mdadm}/lib/udev/rules.d/63-md-raid-arrays.rules:
# Tell systemd to run mdmon for our container, if we need it.
ENV{MD_LEVEL}=="raid[1-9]*",
ENV{MD_CONTAINER}=="?*",
PROGRAM="/usr/bin/readlink $env{MD_CONTAINER}",
ENV{MD_MON_THIS}="%c"
ENV{MD_MON_THIS}=="?*",
PROGRAM="/usr/bin/basename $env{MD_MON_THIS}",
ENV{SYSTEMD_WANTS}+="mdmon@%c.service"

Partially reverts commit 901163c0c707d36323400394bf6e75adc4621e2f.
This has broken remote SSH into initrd because ${cfg.shell} is not
expanded. Also, nsswitch is useless without libnss_files.so which
are installed by initrd-ssh.

packageSet is slated to be introduced in #11866 but currently causes

Setting nixosVersion to something custom is useful for meaningful GRUB
menus and /nix/store paths, but actuallly changing it rebulids the
whole system path (because of `nixos-version` script and manual
pages). Also, changing it is not a particularly good idea because you
can then be differentitated from other NixOS users by a lot of
programs that read /etc/os-release.
This patch introduces an alternative option that does all you want
from nixosVersion, but rebuilds only the very top system level and
/etc while using your label in the names of system /nix/store paths,
GRUB and other boot loaders' menus, getty greetings and so on.
This hopefully fixes intermittent initrd failures where udevd cannot
create a Unix domain socket:
machine# running udev...
machine# error getting socket: Address family not supported by protocol
machine# error initializing udev control socket
machine# error getting socket: Address family not supported by protocol
The "unix" kernel module is supposed to be loaded automatically, and
clearly that works most of the time, but maybe there is a race
somewhere. In any case, no sane person would run a kernel without Unix
domain sockets, so we may as well make it builtin.

This hopefully fixes intermittent test failures like

assuming that these are caused by high load on the host.
... because we make it built-in by default.
I can't imagine anyone who wanted to purge this module from his/her system,
so let's keep it simple, at least for now.
Previously this barfed with:
updating GRUB 2 menu...
fileparse(): need a valid pathname at /nix/store/zldbbngl0f8g5iv4rslygxwp0dbg1624-install-grub.pl line 391.

Clearly it would be the best if we'd directly generate mount units
instead of converting /etc/fstab. But in order to do that we need to
test it throughly so this approach is for the next stable release.
This fix however is intended for inclusion into release-14.12 and
release-15.09.
Using a simple regular expression unfortunately isn't sufficient for
proper mount unit name quoting/escaping and there is a utility in
systemd called systemd-escape which does nothing less than that.
Of course, using an external program to escape the unit name is way more
expensive and causes us to fork for each mount point.
But given that we already do quite a lot of forks just for unit starting
and stopping, I think it doesn't matter that much. Well, except if you
have a whole bunch of mount points.
However, if the latter is the case and you have thousands of mount
points, you probably have stumbled over this already if your mount point
contains a dash.
As for my motivation to fix this: I've stumbled on this while trying to
fix the "none" backend test for NixOps (see NixOS/nixops#350), where the
target machines use /nix/.ro-store and /nix/.rw-store as mount points.
The implementation we had so far did improperly escape it so those mount
points got the following unit files:
* nix-.ro-store.mount
* nix-.rw-store.mount
The correct names for these units are however:
* nix-.ro\x2dstore.mount
* nix-.rw\x2dstore.mount
So using systemd-escape now properly generates these names.
