Bug#774430: systemd: service makes as not reloadable

[Tollef Fog Heen]

Package: systemd
Version: 215-8
Severity: normal
X-Debbugs-Cc: debian-admin at lists.debian.org

It seems systemd believes syslog-ng can't be reloaded for some reason:

minkus% sudo systemctl -p CanReload show syslog-ng.service
CanReload=no

This leads to invoke-rc.d and service failing to reload the service:

minkus% sudo systemctl show syslog-ng.service | grep Relo
ExecReload={ path=/bin/kill ; argv[]=/bin/kill -HUP $MAINPID ; ignore_errors=no ; start_time=[n/a] ; stop_time=[n/a] ; pid=0 ; code=(null) ; status=0/0 }
CanReload=no
NeedDaemonReload=no
minkus% sudo service syslog-ng reload                     
[FAIL] Reload system logging: syslog-ng failed!

If I run invoke-rc.d with sh -x, I get:

[...]
+ testexec /etc/init.d/syslog-ng
+ test 1 -gt 0
+ test -x /etc/init.d/syslog-ng
+ return 0

+ /etc/init.d/syslog-ng reload

+ echo invoke-rc.d: 'initscript syslog-ng, action "reload" failed.'

+ exit 1
