Description Philipp Hahn univentionstaff 2017-03-15 12:20:05 CET
We should convert /etc/init.d/univention-virtual-machine-manager-daemon to a univention-virtual-machine-manager.service
This would allow us to remove runit.

- Replace logging to /var/log/univention/notifier.log (Bug #43685)
- Consider handling of autostart UCRV (Bug #43470)

When replacing runit by systemd, some join scripts/infrastructure must be updated to only start the service after joining:

# find / -xdev \( -name log -o -name dpkg -o -name init.d -o -name cache \) -prune -o -type f -exec grep -n --color /etc/runit/univention {} +

/usr/lib/univention-install/25univention-dhcp.inst:110:ln -s /etc/runit/univention-dhcp /etc/runit/univention/univention-dhcp >/dev/null 2>&1
/usr/lib/univention-install/90univention-bind-post.inst:88:if [ ! -e /etc/runit/univention/univention-bind-proxy ]; then
/usr/lib/univention-install/90univention-bind-post.inst:89:     ln -s /etc/runit/univention-bind-proxy /etc/runit/univention/univention-bind-proxy

/etc/logrotate.d/univention-directory-listener:21: test -x /usr/bin/sv && test -e /etc/runit/univention/univention-directory-listener && sv term univention-directory-listener || true

univention-join also has some internal knowledge of runit:

/usr/share/univention-join/univention-join:665: if [ -e "/etc/runit/univention/$service" ]
/usr/share/univention-join/univention-join:926:if [ -d /etc/runit/univention-directory-notifier ]; then
/usr/share/univention-join/univention-join:931:if [ -d /etc/runit/univention-directory-listener ]; then
