Plymouth falling back to text mode

[Enrico Tagliavini]

Hi Ray,

well moving the udev rules to plymouth module doesn't sounds right to
me, to be honest. If you are using the systemd dracut module, which
uses seats tags (to my knowledge, correct me if I'm wrong), but not
the plymouth dracut module you have the same problem, but the other
way around.

I agree having some file copied twice is not elegant..... but it is
not really wrong. It is like package dependencies, two RPM packages
can both depend on a third one. In this case two dracut modules
depends on these udev rules, so the only right solution is to call
inst_rules in both of them.

It is surely possible to make it more elegant, but this requires quite
some work on dracut (like tracking every file a package wants to
install), and I'm not sure this is worth it.

The point of making the change on plymouth or on dracut..... well I
still think it is better to do that on plymouth, so you don't need a
corresponding change to dracut every time you change something in
plymouth. More over the initrd scripts included in plymouth might be
useful to other initramfs generation tools, so having them including
all the needed files is a good thing.

That said if you prefer to keep this in dracut, I'm very happy with it
as well. We can adjust the dependencies on version with the package
manager so this is a way to solve it. It would be nice to have the
minimum required version stated somewhere though.

I'm also subscribed to the dracut ML, so I can send an email there and
see if anybody has something to say about it, if you like.

Kind regards
Enrico
