Bug#887877: rsyslog start script does not create /dev/xconsole

[Albert 'Tigr' Zenkoff]

Package: rsyslog
Version: 8.24.0-1
Severity: normal
Tags: d-i

Dear Maintainer,

After an upgrade from Debian jessie to stretch, the /dev/xconsole has disappeared. It seems that the scripts of systemctl take over the start of the daemon and the start/stop functions in the actual rsyslog script in init.d are no longer run. The script contains a function that creates /dev/xconsole pipe at startup. Since the script is no longer run, the pipe is not created, rsyslogd does not write there and the applications reading from the pipe fail.

For the time being, I have modified the startup script for rsyslog to run the create_xconsole() function at the beginning of the script and it works. It would be great that the /dev/xconsole was created by the system without such need of tweaking.

Cheers,
Albert
