Being wanted by and ordered before local-fs.target isn't strictly
correct. And in systemd initrd, it's very incorrect because
local-fs.target is for the initrd file system, not the real root file
system.
a zfs fileSystems entry with an absolute (e.g. device) path rather than
a zfs dataser is parsed as an empty pool name, causing a doomed-to-fail
import job to be created as a boot dependency. Catch this as an assertion
Currently systemd-ask-passwd times out after 1m30s. After 3 tries this
causees systemd to enter the emergency shell and basically lead to an
unbootable system requiring a reboot to be able to try to unlock again.
Also if a pool is imported but not unlocked, the unlock step will no
longer be skipped.
Enable using an erofs filesystem as one of the filesystems needed to
boot the system. This is useful for example in image based deployments
where the Nix store is mounted read only.
[erofs](https://docs.kernel.org/filesystems/erofs.html) offers multiple
benefits over older filesystems like squashfs. Skip fsck.erofs because
it is still experimental.
According to a ZFS issue about hibernation causing data corruption:
https://github.com/openzfs/zfs/issues/12842
The way this happens is if the system force imports a pool that was
suspended during hibernation. I've had this happen twice on NixOS and
I'd like to avoid having this happen again, to me or others.
To do this I've added an assertion that makes sure you can't have
`forceImportRoot` or `forceImportAll` enabled with `allowHibernation`.

conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
...if cfgExpandOnBoot == "all", otherwise it fails during runtime:
```
Aug 06 19:38:05 nixos zpool-expand-pools-start[981]: /nix/store/ka3vivdray82mi9dql12yf258gkw643l-unit-script-zpool-expand-pools-start/bin/zpool-expand-pools-start: line 3: zpool: command not found
```
now nix-doc-munge will not introduce whitespace changes when it replaces
manpage references with the MD equivalent.
no change to the manpage, changes to the HTML manual are whitespace only.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
