zfs.target wanted by multi-user.target is too late

[Hadmut Danisch]

Hi,

could it be possible that

/lib/systemd/system/zfs.target

has a wrong dependency

WantedBy=multi-user.target

and shouldn't it be wanted by local-fs.target instead?

Reason I'm asking:

I do have to install a daemon on several machines, where a particular work directory is on zfs only on some machines. To start my daemon, I therefore use

[Unit]
After=network.target
After=local-fs.target

[Install]
WantedBy=multi-user.target

but found that the daemon fails to start, because zfs mount isn't ready yet. systemd simply doesn't know that my daemon needs zfs up and running on those machines, where zfs is installed.

Of course, I could easily add After=zfs.target, but that would fail on those machines without zfs and would not be really clean.

Doesn't having zfs being wanted as late as multi-user.target break the systemd logic that after local-fs.target all local file systems should be ready, and daemons are to be started between local-fs.target and and multi-user.target?

regards
