Bug#802210: systemd: Shutdown delay waiting for stop events

[Aryeh Leib Taurog]

Package: systemd
Version: 215-17+deb8u2
Severity: normal

Dear Maintainer,

I just recently upgraded from wheezy to jessie.  The /home partition 
is LUKS encrypted.

Shutdown always takes 90s while waiting for various stop events to 
time out.  At first these seemed not always to be the same, but the 
last several times I shut down, the culprits were:

    * Monitoring of LVM2 mirrors
    * Device Mapper event daemon

I have a number of lvm volumes, but I don't think I actually have any 
mirrors.  Can the first of these be disabled altogether?

Thanks,
Aryeh Leib Taurog
