Subject: Secure Attention Key kills console-kit-daemon
Date: Mon, 24 Aug 2009 10:21:14 +0200
Package: consolekit
Version: 0.3.0-3+b1
Severity: normal


pressing the Secure Attention Key kills all processes that have a /dev/tty
handle open; console-kit-daemon happens to be one of them (actually, all
threads receive a separate SIGKILL, which is very noisy).

Despite not knowing what I actually need this process for, I think it might
be bad for it to be stopped if some other tool or library expects it to
exist when it doesn't, so I think the daemon should be made to set itself
up in a way that pressing the SAK does not kill it entirely (e.g. perhaps a
separate process for /dev/tty1, and not keeping a /dev/tty handle).
