From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Stoiko Ivanov Date: Tue, 15 Sep 2020 19:07:24 +0200 Subject: [PATCH] Add systemd-unit for importing specific pools The unit can be instantiated with a specific poolname, which will get imported by scanning /dev/disk/by-id, irrespective of the existence and content of /etc/zfs/zpool.cache. the instance name is used unescaped (see systemd.unit(5)), since zpool names can contain characters which will be escaped by systemd.
