but that should then be presumably raised as an issue with dracut-ng as if it worked with the old dracut it should work with dracut-ng as version 100 was said to be a drop-in replacement for the old version.

We are currently on version 108 and I just found in the changelog for that version the following change.

--------------------------
feat(initqueue): factor out initqueue into its own module
This PR allows excluding dracut initqueue module, while
including the base or the dracut-systemd module.

Factoring out functionality into its own module
allows to better control to include or exclude the
functionality.
--------------------------

https://github.com/dracut-ng/dracut-ng/commit/3daf67830d8db3b12bc45eef9f8f29f606192db9

So it looks like it is a module that has to be explicitly specified now whereas in the past it was part of dracut base.

Regards,

Adolf.

>>> The problem was that I made a clone of a system that I had tested out upgrading from CU150 to CU198 and the boot size was obviously smaller back in CU150 as I only have 110MB but the more current systems have 488MB so I will create a clone of one of my newer systems and repeat the test.
