Bug#845186: systemd: does not respect ctrl-c running into timeout when starting or stopping services

[Martin Steigerwald]

Package: systemd
Version: 232-5
Severity: normal

Dear Martin, dear Michael, dear Maintainers,

as I added a removable LUKS crypto device to fstab like in

/dev/mapper/someluksdevice /mnt/somemountpoint      btrfs           noatime,autodefrag,compress=lzo          0       0

I forgot to add "noauto".

Consequently systemd ran into a timeout of 90 seconds that was not
interruptible.

On the other hand atopacctd from experimental right now does not respond to
SIGTERM properly at the moment, again leading into a 90 seconds timeout,
that again is not interruptible with Ctrl-C.


Actual results

Pointless waiting. I know the action is not going to succeed. I know this
*better* than systemd. Frustration cause I get the impression systemd tries
to control me while I think it should be the other way around.


Expected results

When I press Ctrl-C when systemd runs into a timeout, I expect systemd
to execute my command as soon as possible. Cause actually I know better
than systemd in that cases and waiting for the completion of the timeout
is pointless.

I have some understanding that systemd may not allow Ctrl-C in all circum-
stances, since it may be possible that someone tries to hack the boot
process by just pressing Ctrl-C, but when systemd notices that it runs
into a timeout and displaying so I expect it to give an option to tell it
to stop waiting pointlessly.


I think this is an upstream issue. Feel free to forward it. I don´t feel
like arguing with systemd upstream myself given my past experiences on
systemd developer mailinglist, please respect that.

Thank you,
Martin
