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.

This resolves the issue by treating an zero-length cache files the

Closes#10559
== 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

If /var/lib is a dataset not under <pool>/ROOT/<root_dataset>, as
proposed in the ubuntu root on zfs upstream guide
(https://github.com/zfsonlinux/zfs/wiki/Ubuntu-18.04-Root-on-ZFS),
we end up with a race where some services, like systemd-random-seed
are writing under /var/lib, while zfs-mount is called. zfs mount will
then potentially fail because of /var/lib isn't empty and so, can't be
mounted.
Order those 2 units for now (more may be needed) as we can't declare
virtually a provide mount point to match
"RequiresMountsFor=/var/lib/systemd/random-seed" from
systemd-random-seed.service.
The optional generator for zfs 0.8 fixes it, but it's not enabled
by default nor necessarily required.
Example:
- rpool/ROOT/ubuntu (mountpoint = /)
- rpool/var/ (mountpoint = /var)
- rpool/var/lib (mountpoint = /var/lib)
Both zfs-mount.service and systemd-random-seed.service are starting
After=systemd-remount-fs.service. zfs-mount.service should be done
before local-fs.target while systemd-random-seed.service should finish
before sysinit.target (which is a later target).
Ideally, we would have a way for zfs mount -a unit to declare all paths
or move systemd-random-seed after local-fs.target.

* contrib/initramfs: include /etc/default/zfs and /etc/zfs/zfs-functions
At least debian needs /etc/default/zfs and /etc/zfs/zfs-functions for
its initramfs. Include both in build when initramfs is configured.
* contrib/initramfs: include 60-zvol.rules and zvol_id
Include 60-zvol.rules and zvol_id and set udev as predependency instead
of debians zdev. This makes debians additional zdev hook unneeded.
* Correct initconfdir substitution for some distros
Not every Linux distro is using @sysconfdir@/default but @initconfdir@
which is already determined by configure. Let's use it.
* systemd: prevent possible conflict between systemd and sysvinit
Systemd will not load a sysvinit service if a unit exists with the same
name. This prevents conflicts between sysvinit and systemd.
In ZFS there is one sysvinit service that does not have a systemd
service but a target counterpart, zfs-import.target.
Usually it does not make any sense to install both but it is possisble.
Let's prevent any conflict by masking zfs-import.service by default.
This does not harm even if init.d/zfs-import does not exist.

When a system boots the zfs-mount.service and the
zfs-share.service can start simultaneously. What may be
unclear is that sharing a filesystem will first mount
the filesystem if it's not already mounted. This means
that both service can race to mount the same fileystem.
This race can result in a SEGFAULT or EBUSY conditions.
This change explicitly defines the start ordering between the
two services such that the zfs-mount.service is solely
responsible for mounting filesystems eliminating the race
between "zfs mount -a" and "zfs share -a" commands.

The zfs-volume-wait.service scans existing zvols and waits for their
links under /dev to be created. Any service that depends on zvol
links to be there should add a dependency on zfs-volumes.target.
By default, this target is not enabled.

Modify zfs-mount-generator to produce a dependency on new
zfs-import-key-*.service units, dynamically created at boot to call
zfs load-key for the encryption root, before attempting to mount any
encrypted datasets.
These units are created by zfs-mount-generator, and RequiresMountsFor on
the keyfile, if present, or call systemd-ask-password if a passphrase is
requested.
This patch includes suggestions from @Fabian-Gruenbichler, @ryanjaeb and
@rlaager, as well an adaptation of @rlaager's script to retry on
incorrect password entry.

Alternative implementation of @rlaager's original modification
of zfs-mount-generator fix, with @chrisrd's comments. Set
IFS to be only the tab character, matching our `-H` call in
`zfs list`, allowing spaces to appear in dataset names (and
mountpoints).
Also adds comments explaining our rationale.
