Severity: normal

Dear dmsetup maintainers,
when debugging #731208 and #712439 I noticed that dmsetup in Debian does
not ship an important bit of the upstream rules files (specifically
udev/13-dm-disk.rules.in): The OPTIONS+="watch" for device mapper
devices is not included.
Enabling the watch option (which will generate a udev event once the
device is closed after being open for writing) is crucial for an
event-based boot with encrypted swap. After setting up the encryption
with a random key, the init system (systemd in this case) calls mkswap
and waits for the event to arrive. Once it gets notified, it calls
swapon.
Therefore, I ask you to please apply this patch to your rules, or make
the change in any other way you see fit, as long as the watch option
gets enabled:
--- /lib/udev/rules.d/55-dm.rules 2013-08-07 09:45:01.000000000 -0400

Thank you,
