Comment # 5 on bug 1231325 from Alberto Planas Dominguez

@Andrei, based on your idea of the generator I am preparing something like
this:

https://github.com/aplanas/dracut-pcr-signature/pull/4

Is still a draft as I am doing something wrong when making the service wanted
in some target. For example, if I add it to cryptsetup.target.wants/ then the
cycle is something like:

[    2.579258][    T1] systemd[1]: No hostname configured, using default
hostname.
[    2.580325][    T1] systemd[1]: Hostname set to <localhost>.
[    2.762644][    T1] systemd[1]: sysinit.target: Found ordering cycle on
cryptsetup.target/start
[    2.763712][    T1] systemd[1]: sysinit.target: Found dependency on
pcr-signature.service/start
[    2.764745][    T1] systemd[1]: sysinit.target: Found dependency on
basic.target/start
[    2.765713][    T1] systemd[1]: sysinit.target: Found dependency on
sysinit.target/start
[    2.766668][    T1] systemd[1]: sysinit.target: Job cryptsetup.target/start
deleted to break ordering cycle starting with sysinit.target/start
[ SKIP ] Ordering cycle found, skipping Local Encrypted Volumes

And then I add it to initrd.target.wants, the cycle gets extended with a "Found
dependency or cryptsetupt-pre.target/start"

I would love a review from your side on the code, but I think that if I figure
out the cycle issue this could resolve the races in the code.
