systemd can statically load kernel modules at boot. This is done by
placing appropriate files *.conf in /etc/modules-load.d. To be
compatible with initmethod-busybox (e.g. if you switch between both)
just a symlink to /etc/modules is created like Debian does, too.

PTXdist doesn't really support switching the initmethod at runtime. I'd
prefer to just install /etc/modules-load.d/modules.conf. If you need both
you can add the symlink in projectroot.

Hello Michael,

I'm aware of this. I guess there's no system like this and there's no
need to. What I do is switching those for development, build a new
image and test it afterwards. I would have only one file then in
projectroot in my BSP and it would be handy for me.

So just add an empty generic/etc/modules-load.d/modules.conf to
ptxdist and call install_alternative if someone says yes to
PTXCONF_INITMETHOD_SYSTEMD_MODULES_LOAD?
