From 55d80e651a8c19919b8ee6a1c05fb36ad97ab5ad Mon Sep 17 00:00:00 2001 From: Antonio Russo Date: Fri, 6 Apr 2018 17:11:09 -0400 Subject: systemd mount generator and tracking ZEDLET MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
