If you believe parted_server (which is in the partman-base package)
needs improvements, please clone this bug and reassign the clone to
partman-base. Keeping this bug open for that would make tracking too
difficult.
Ok. I can now reproduce the partman-base problem, using a specially
created crash prone /lib/libparted.so.0.0.1 library. The parted-server,
as expected, crash this way on the console it has been started from:
r...@point:/home/jcdr/partman-base-test# bin/parted_server

The /var/lib/partman/outfifo simply report:
OK
OK
And /var/log/partman say:
parted_server: ======= Starting the server
parted_server: main_loop: iteration 1
parted_server: Opening infifo
parted_server: Read command: OPEN
parted_server: command_open()
parted_server: Request to open =dev=sdb
parted_server: Opening outfifo
parted_server: OUT: OK
parted_server: OUT: OK
So I think it's not really parted_server the cause of the problem (is
case of libparted problem), but more the script that started it and
failed to observe that it crashed.
Still, this script probably in partman-base too.
But what do you say by "clone this bug" ?
* It there a procedure to do this ?
* Or it's a administrative option I don't have access to as a user ?
* Or I have to manually copy the report into a new one ?
