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.
|
