Hi Dmitry,
Please consider add those --auto/--noauto options to update-service: noauto
prevent an already enabled
service to restart if it's terminated and prevent to automatically start a
service at boot.
Somehow a duplicate of 'sv d service' or 'update-service --remove', but is also
different in
that (unlike 'sv d service') it persist across reboot and also (unlike
update-service --remove)
does not need to act on symlink. Maybe could be useful, see if you like it.
The patch add --auto/--noauto options and also update the manpage to describe
those options.
Lorenzo

Subject: [PATCH 2/2] Add --auto/--noauto option to update-service
'noauto' touches a down file inside the service directory, preventing
the service from automatically start at boot;
'auto' removes the down file restoring the default behavior.
Also update synopsis and description of update-service's man page.
