As I wanted to use custom kernel parameters (boot options), I
that it seems that there is no way to set custom settings that will be
integrated in systemd-boot's entry configuration files each
time the kernel is updated, is there?
This is BUG in our post-update script.
I will start with the fix.
One of our statements said: if a user modify systemd-boot config file,
post-update script won't alter config file.
