|

zfs\-mount\-generator implements the \fBGenerators Specification\fP
|

of
|
||||
.BR systemd (1),
|

and is called during early boot to generate
|

.BR systemd.mount (5)
|

units for automatically mounted datasets. Mount ordering and dependencies
|
||||
are created for all tracked pools (see below).
|
||||
|
||||
.SS ENCRYPTION KEYS
|
||||
If the dataset is an encryption root, a service that loads the associated key (either from file or through a
|
||||
.BR systemd\-ask\-password (1)
|
||||
prompt) will be created. This service

Additionally, unless the pool the dataset resides on

|
||||
.Sy Wants Ns = Ns Pa zfs-import.target
|
||||
and
|
||||
.BR Requires .
|
||||
All mount units of encrypted datasets add the key\-load service for their encryption root to their
|
||||
.BR Wants
|
||||
and
|
||||
.BR After .
|
||||
The service will not be

.BR Require d
|

|
||||
.BR local-fs.target
|

directly, and so will only be started manually or as a dependency of a started mount unit.

|

.BR After
|
||||
|
||||
It is worth nothing that when a mount unit is activated, it activates all available mount units for parent paths to its mountpoint, i.e. activating the mount unit for /tmp/foo/1/2/3 automatically activates all available mount units for /tmp, /tmp/foo, /tmp/foo/1, and /tmp/foo/1/2. This is true for any combination of mount units from any sources, not just ZFS.

The behavior of the generator script can be influenced by the following dataset properties:
|

.sp
|

.TP 4
|

.BR canmount = on | off | noauto
|

If a dataset has
|

.BR mountpoint
|

set and
|
||||
.BR canmount
|
||||
is not
|
||||
.BR off ,
|

a mount unit will be generated.
|

Additionally, if
|

.BR canmount
|
||||
is
|

.BR on ,
|
||||
.BR local-fs.target
|
||||
will gain a dependency on the mount unit.
|

|

Then, enable the tracking ZEDLET:

.RE
|

.PP
|
||||
Force the running of the ZEDLET by setting a monitored property, e.g.
|

.BR canmount ,
|
||||
for at least one dataset in the pool:

|
||||
.I DATASET
|
||||
.RE
|
||||
.PP
|
||||
This forces an update to the stale cache file.
|
||||
|
||||
To test the generator output, run
|

.PP
|

.RS 4
|
||||
@systemdgeneratordir@/zfs-mount-generator /tmp/zfs-mount-generator
|

|

If no history event is in the queue,

inject one to ensure the ZEDLET runs to refresh the cache file

by setting a monitored property somewhere on the pool:
