etc/systemd/zfs-mount-generator: rewrite in C 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 See PR for detailed timings (of an early version) and diffs Reviewed-by: Antonio Russo <aerusso@aerusso.net> Reviewed-by: Richard Laager <rlaager@wiktel.com> Reviewed-by: InsanePrawn <insane.prawny@gmail.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Issue #11915 Closes #11917

Centralize variable substitution A bunch of places need to edit files to incorporate the configured paths i.e. bindir, sbindir etc. Move this logic into a common file. Create arc_summary by copying arc_summary[23] as appropriate at build time instead of install time.

systemd mount generator and tracking ZEDLET zfs-mount-generator implements the "systemd generator" protocol, producing systemd.mount units from the cached outputs of zfs list, during early boot, integrating with systemd. Each pool has an indpendent cache of the command zfs list -H -oname,mountpoint,canmount -tfilesystem -r $pool which is kept synchronized by the ZEDLET history_event-zfs-list-cacher.sh Datasets not in the cache will be loaded later in the boot process by zfs-mount.service, including pools without a cache. Among other things, this allows for complex mount hierarchies.
