[Pkg-sysvinit-devel] Bug#705254: Provice "is-enabled" command for update-rc.d

[Michael Biebl]

Package: sysv-rc
Version: 2.88dsf-41
Severity: wishlist
File: /usr/sbin/update-rc.d
User: pkg-systemd-maintainers at lists.alioth.debian.org
Usertags: integration

Hi Roger,

as briefly discussed on IRC, I'd like to see a "is-enabled" command
added to update-rc.d which can be used to query, if a SysV init script
has been enabled or not.

The update-rc.d enable|disable interface is vastly superior to the
DISABLED flags in /etc/default/foo config files and the is-enabled
command would suplement that.

One area where we would like to make use of the "is-enabled" command is
for packages whish want to add support for systemd.
When packages add native systemd service files, the initial state of the
systemd service should be based on what the SysV service is using.
I.e., if a SysV service has been disabled by the system administrator,
this should be respected by the systemd service, too. For that we need
to be able to query the state of the SysV service when the package is
upgraded.

Cheers,
Michael
