Hi!

I just wanted to point out that booting Qubes OS 4.1 still hangs with
today's updates being applied to Dom0. I have to add
"systemd.mask=lvm2-monitor".

Regards,
Ulrich

As I learned recently that I can start a debug shell on tty9 using boot
parameter "systemd.debug_shell=1", I inspected what's going on when
things seem to hang.
It seems the a "vgchange --monitor y" is running for an extended time.
However when I run that command manually, I get a syntax error!

When I run the command "vgchange --monitor y qubes_dom0" it exits
immediately.

So it looks to me that some incorrect command is run by systemd.

I'm attaching a photo of my debug session.
