etc/init.d: decide which variant to use at build time.
Let Debian use the sysv-rc variant of the script, even when OpenRC is
installed. Unlike on Gentoo, OpenRC on Debian consumes both the
sysv-rc scripts and OpenRC ones. ZFS initscripts on Debian should be
the sysv-rc version to provide most compatibility and to integrate
with the rest of initscripts for dependency tracking.

Restrict the substitution in the Makefile to the dedicated list.

This construct is inspired by Mo Zhou's detection of the execution
shell and follows the strategy of Peter in 6ef28c526b.

As of 2024, the initscripts are mostly relevant on Debian, Gentoo and
their derivatives.

systemd: Use non-absolute paths in Exec* lines
Since systemd v239, Exec* binaries are resolved from PATH when they
are not-absolute. Switch to this by default for ease of downstream
maintenance. Many downstream distributions move individual binaries
to locations that existing compile-time configurations cannot
accommodate.

etc/systemd/zfs-mount-generator: avoid strndupa
The non-standard strndupa function is not implemented by musl libc,
and can be dangerous due to its potential to blow the stack.  (musl
_does_ implement strdupa, used elsewhere in this function.)

With a similar amount of code, we can use a heap allocation to
construct the pool name, which is musl-friendly and doesn't have
potential stack problems.

(Why care about musl when systemd only supports glibc?  Some distros
patch systemd with portability fixes, and it would be nice to be able
to use ZFS on those distros.)

Make zfs-share service resilient to stale exports
The are a few cases where stale entries in /etc/exports.d/zfs.exports 
will cause the nfs-server service to fail when starting up.

Since the nfs-server startup consumes /etc/exports.d/zfs.exports, the 
zfs-share service (which rebuilds the list of zfs exports) should run 
before the nfs-server service.

To make the zfs-share service resilient to stale exports, this change 
truncates the zfs config file as part of the zfs share -a operation.

Replace EXTRA_DIST with dist_noinst_DATA
The EXTRA_DIST variable is ignored when used in the FALSE conditional
of a Makefile.am.  This results in the `make dist` target omitting
these files from the generated tarball unless CONFIG_USER is defined.
This issue can be avoided by switching to use the dist_noinst_DATA
variable which is handled as expected by autoconf.

This change also adds support for --with-config=dist as an alias
for --with-config=srpm and updates the GitHub workflows to use it.

ad9e767657 linux: module: weld all but spl.ko into zfs.ko
Originally it was thought it would be useful to split up the kmods
by functionality.  This would allow external consumers to only load
what was needed.  However, in practice we've never had a case where
this functionality would be needed, and conversely managing multiple
kmods can be awkward.  Therefore, this change merges all but the
spl.ko kmod in to a single zfs.ko kmod.

A plain rewrite of the shell version, and generates identical
units, save for replacing some empty lines with nothing, having fewer
meaningless spaces in After=s and different spacing in the lock scripts,
for a clean git diff -w

This is a gain of anywhere from 0m0.336s vs 0m0.022s (15.27x)
to 0m0.202s vs 0m0.006s (33.67x), depending on the hardware,
a.k.a. from "absolutely unusable" to "perfectly fine"

This also properly deals with canmount=noauto units across multiple
pools

zfs-import-{cache,scan}: change condition to FileNotEmpty
When all pools are exported ZFS will generate an empty cache file.
This will cause the import service to fail, which is sub-optimal, 
since this means that dracut fails, and it necessary to run 
`zpool import -a` to boot, delete the file, and regenerate+reinstall 
the initrd.

This resolves the issue by treating an zero-length cache files the
same as a missing cache file.  This aligns the behavior with that
of the `zpool` command itself.

62663fb7ec Fix another dependency loop
zfs-load-key-DATASET.service was gaining an
After=systemd-journald.socket due to its stdout/stderr going to the
journal (which is the default).  systemd-journald.socket has an After
(via RequiresMountsFor=/run/systemd/journal) on -.mount.  If the root
filesystem is encrypted, -.mount gets an After
zfs-load-key-DATASET.service.

By setting stdout and stderr to null on the key load services, we avoid
this loop.

b717f9b95e BindsTo dataset keyload unit to mount associate unit
We need a stronger dependency between the mount unit and its keyload unit
when we know that the dataset is encrypted.
If the keyload unit fails, Wants= will still try to mount the dataset,
which will then fail.
It’s better to show that the failure is due to a dependency failing, the
keyload unit, by tighting up the dependency. We can do this as we know
that we generate both units in the generator and so, it’s not an
optional dependency.
BindsTo enable as well that if the keyload unit fails at any point, the
associated mountpoint will be then unmounted.

Drop Before=zfs.mount dependency explicity on generated key-load .service
unit.
Indeed, the associated mount unit is After=<dataset-key-load>.service.
This is thus the mount point which controls at what point it wants to be
mounted (Before=zfs-mount.service in stock generator), but this can be
an automount point, or triggered by another service.
This additional dependency from the key load service is not needed thus.

Remove dependency on sharetab file and refactor sharing logic
== Motivation and Context

The current implementation of 'sharenfs' and 'sharesmb' relies on
the use of the sharetab file. The use of this file is os-specific
and not required by linux or freebsd. Currently the code must
maintain updates to this file which adds complexity and presents
a significant performance impact when sharing many datasets. In
addition, concurrently running 'zfs sharenfs' command results in
missing entries in the sharetab file leading to unexpected failures.

== Description

This change removes the sharetab logic from the linux and freebsd
implementation of 'sharenfs' and 'sharesmb'. It still preserves an
os-specific library which contains the logic required for sharing
NFS or SMB. The following entry points exist in the vastly simplified
libshare library:

- sa_enable_share -- shares a dataset but may not commit the change
- sa_disable_share -- unshares a dataset but may not commit the change
- sa_is_shared -- determine if a dataset is shared
- sa_commit_share -- notify NFS/SMB subsystem to commit the shares
- sa_validate_shareopts -- determine if sharing options are valid

The sa_commit_share entry point is provided as a performance enhancement
and is not required. The sa_enable_share/sa_disable_share may commit
the share as part of the implementation. Libshare provides a framework
for both NFS and SMB but some operating systems may not fully support
these protocols or all features of the protocol.

NFS Operation:
For linux, libshare updates /etc/exports.d/zfs.exports to add
and remove shares and then commits the changes by invoking
'exportfs -r'. This file, is automatically read by the kernel NFS
implementation which makes for better integration with the NFS systemd
service. For FreeBSD, libshare updates /etc/zfs/exports to add and
remove shares and then commits the changes by sending a SIGHUP to
mountd.

SMB Operation:
For linux, libshare adds and removes files in /var/lib/samba/usershares
by calling the 'net' command directly. There is no need to commit the
changes. FreeBSD does not support SMB.

== Performance Results

To test sharing performance we created a pool with an increasing number
of datasets and invoked various zfs actions that would enable and
disable sharing. The performance testing was limited to NFS sharing.
The following tests were performed on an 8 vCPU system with 128GB and
a pool comprised of 4 50GB SSDs:

Scale testing:
- Share all filesystems in parallel -- zfs sharenfs=on <dataset> &
- Unshare all filesystems in parallel -- zfs sharenfs=off <dataset> &

Functional testing:
- share each filesystem serially -- zfs share -a
- unshare each filesystem serially -- zfs unshare -a
- reset sharenfs property and unshare -- zfs inherit -r sharenfs <pool>

For 'zfs sharenfs=on' scale testing we saw an average reduction in time
of 89.43% and for 'zfs sharenfs=off' we saw an average reduction in time
of 83.36%.

Functional testing also shows a huge improvement:
- zfs share -- 97.97% reduction in time
- zfs unshare -- 96.47% reduction in time
- zfs inhert -r sharenfs -- 99.01% reduction in time
