Package: ifupdown
Version: 0.8.35
Severity: important
File: /var/lib/dpkg/info/ifupdown.prerm
Dear Maintainer,
When removing the ifupdown package, for example if one replaces it with
ifupdown2, the premrm script will execute a `systemctl stop` to the
'networking.service'. If one is connect to the host over network (e.g.,
SSH), the connection is broken during this removal/replacement.
This is really no ideal, especially if one has no other access to this
host available.
Simple reproducer could be:
# apt install ifudown2
It would be great if the stop of 'networking.services' would be avoided,
similar to how the start on upgrade or installation is avoided. I'd
expect that such deep network changes are only fully applied
automatically on the next reboot, or by a manual triggered process.
I reported this as important, even if the description from `reportbug`
may not fully match that, but I still found me in a bit troubling
situation when I encountered this, so IMO it's justified - but feel free
to adjust as deemed right, I'm no maintainer after all :)
thanks & cheers,
Thomas
