Yeap. I just need to check what ended up being mounted where and what
the .mount units that got generated actually look like.
That is why I am asking wether somebody knows how to get a debug shell.

There is no /usr in fstab:-) Getting /usr mounted based on
/proc/cmdline is what I am experimenting with and I might just have
ended up messing up the mount options, getting me something else on
/usr than whatever I expect.
My C-foo is a bit rusty, so who knows what I actually put into my
patched version of systemd-fstab-generator that I have on that

chroot works fine, once I manually mounted the root and /usr FS to
I guess the next stop is getting a debug shell into the initrd. "man
systemd-debug-generator" should have all the information I need for
that, I hope.
But first I need to check whether removing "quiet" has any useful effect.
