[systemd-devel] /etc/fstab dependences migrated between units due to automount feature

[Daniel Otero Oubiña]

Hi all!

I have found a somehow strange systemd "feature" that I'm not sure if it's
a bug. Let me know if you prefer having this reported on GitHub instead.

First, let me explain my setup: I have a data filesystem that is split in
two encrypted partitions (with LUKS) formated as a single btrfs raid1
filesystem.
I manage to make everything work just modifying fstab and crypttab.

The problem arises when I try to make the data partition mounted on demand
(`x-systemd.automount`). That's because it makes my "decrypted partitions"
dependences (declared with `systemd.requires=systemd-cryptsetup at xxx.service`)
move from the .mount autogenerated unit to the .automount one. This causes
the partitions to be decrypted even if the data filesystem is never used,
because the .automount unit is activated on boot. Is there a reasoning for
this behavior or I'm missing something?

Here is a link with the autogenerated units with and without the automount
option:

Thanks!
