Hi,
I have just joined this list. I am a newcomer to using device-mapper.
I currently maintain Quirky Linux, prior to that, Puppy Linux. Puppy
uses overlay filesystems, usually aufs, to achieve what could also be
done, partly, with device-mapper.
Puppy has a initramfs, however, Quirky is a traditi
Hi Martin,
Nice to see you, May you success in your team and our open source
community.
You have put forward a good proposal to queued more uevent messages by
kicking uevent
processing thread in a predefined time intervals. It is also a good idea
to have such intervals
configuration.

(Please still consider it to be RFC only, I need to modify the uspace teststuite
again due to changes in key_string format. Also the changes to dm-crypt

Hello Mike,
With patch (a) applied I see warning (b) appear a few seconds after I

Hello Hannes:
Since the received uevent messages store in the queue, and the speed
uevent messages received is
much faster than the speed uevent messages processed, so, we can merge
these queued uevent
