cryptsetup-generator: run cryptsetup service before swap unit (#5480)
If the cryptsetup service unit and swap unit for a swap device
are not strictly ordered, it might happen that the swap unit
activates/mounts the swap device before its cryptsetup service unit
has a chance to run the 'mkswap' command (that it is programmed to).
This leads to the following error:
Starting Cryptography Setup for sda3_crypt...
[ OK ] Found device /dev/mapper/sda3_crypt.
Activating swap /dev/mapper/sda3_crypt...
[ OK ] Activated swap /dev/mapper/sda3_crypt.
[ OK ] Reached target Swap.
[FAILED] Failed to start Cryptography Setup for sda3_crypt.
See 'systemctl status systemd-cryptsetup@sda3_crypt.service' for
details.
[DEPEND] Dependency failed for Encrypted Volumes.
Which happens because the swap device is already mounted:
# systemctl status systemd-cryptsetup@sda3_crypt.service
<...>
Active: failed (Result: exit-code) since Mon 2017-02-27 14:21:43 CST;

<...>
<...> systemd[1]: Starting Cryptography Setup for sda3_crypt...
<...> mkswap[2420]: mkswap: error: /dev/mapper/sda3_crypt is mounted;
will not make swapspace
<...>
So, modify cryptsetup-generator to include a 'Before=' option for the
respective 'dev-mapper-%i.swap' device in the cryptsetup service unit.
Now, correct ordering is ensured, and the error no longer occurs:
Starting Cryptography Setup for sda3_crypt...
[ OK ] Found device /dev/mapper/sda3_crypt.
[ OK ] Started Cryptography Setup for sda3_crypt.
Activating swap /dev/mapper/sda3_crypt...
[ OK ] Reached target Encrypted Volumes.
[ OK ] Activated swap /dev/mapper/sda3_crypt.
[ OK ] Reached target Swap.
