automatic startup of iSCSI swap (systemd)

[mounty1]

Hello, the usual way of automatically starting swap is to add an entry to /etc/fstab. However, in the case of swap on iSCSI there is a dependency problem inasmuch as /etc/fstab is obeyed earlier in the startup process than iscsid, so the iSCSI block device is not available when /etc/fstab is obeyed.

In this situation, what is the best-practice way of adding the swap? Is it to write a systemd unit that depends on the iscsid service?

Please note I am asking about best practice as opposed to random opinions. Thank you.

Best practice is what OpenRc does - which is /etc/init.d/swap, which calls "swapon -a", and you can read about it in the swapon man page.
I guess second best practice is what systemd does, i.e. something overcomplicated that seems to need generating, or at least that's what the Arch wiki says.
(At least reading that explains why my Arch systems use swap partitions I never told it about through /etc/fstab. I prefer software that does what it's told, not what it thinks I want...)

Your mileage will vary.
