Hi,

Thanks for the report.

I cannot reproduce the bug by installing lvm2 on sid or jessie.

Why was mountdevsubfs not enabled?

Could you please paste the output of "ls -l /etc/rc*.d/*mountdev*" and
"rc-update | grep mountdev"?

On my system, they produce:

# ls -l /etc/rc*.d/*mountdev*
lrwxrwxrwx 1 root root 26 Feb 18 23:16 /etc/rcS.d/S02mountdevsubfs.sh -> ../init.d/mountdevsubfs.sh

# rc-update | grep mountdev
     mountdevsubfs.sh |                                    sysinit

Did it hang with openrc?

Didn't openrc+lvm2 hang? Confused:(

The new update-rc.d from init-system-helpers calls rc-update to handle
the runlevels for openrc.  It is different from the old update-rc.d
shipped with openrc only in that it also calls insserv, too.

So the question really becomes: is your mountdevsubfs.sh enabled?
