Package: udev
Version: 240-2
Severity: critical
Justification: Breaks whole system
Hi,
I have no idea why this is happening, but several packages use "udevadm
control --reload-rules" in their postinst (e.g. fuse) and if that's run,
all process except init are instantly killed (reproducibly; the gettys
seem to be respawned by init then, so I can login locally again) and
since sshd is killed, too, the system is usually no more accessible from
remote (hence the severity "critical") despite still responding to ping
replies.
There's nothing in dmesg. And corekeeper didn't catch any core either.
Some more details which might be helpful:
* The udev daemon itself also vanishes and this happens independently of
the udev daemon being running or not (i.e. "service udev start" before
calling udevadm doesn't prevent this from happening).
* The other two udevadm command from fuse's postinst don't seem to
trigger this:
udevadm test --action -p $(udevadm info -q path -n /dev/fuse)
* It first happened when I install linux-image-4.20-trunk-amd64 from
experimental about a week ago or so. Since I was away from home until
yesterday evening, I could only recently start to debug this.
Here's an strace of that command:
