Bug 803878 – emerge -av --depclean wants to remove openrc.

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Alan Mackenzie 2021-07-24 18:41:24 UTC]

This occurs in my openrc system with sys-process/daemontools installed.
(Note daemontools is needed for qmail (an mta) to function.)

Reproducible: Always

Steps to Reproduce:
1. emerge sys-process/daemontools.
2. emerge -av --depclean.
3. DON'T type 'y'.
Actual Results:  
One of the packages emerge proposes to remove is openrc.  A careless use of --depclean could leave a system unbootable.

Expected Results:  
--depclean leaves in place all packages required to boot a system, and also those needed for rudimentary maintenance (e.g. nano).

(Thanks to Neil Bothwick and Rich Freeman for help in tracking this bug down.)

The problem is in virtual/service-manager/service-manager-1.ebuild where virtual/daemontools appears to be deemed an equal of openrc, systemd, runit, etc.  At a guess, since daemontools is in @world, --depclean won't remove it, and removes openrc instead.

Suggestion: Packages in @system should not be removed by --depclean, unless, possibly, this is specifically requested by the user.

OpenRC is pulled into the system set via virtual/service-manager. If you install sys-process/daemontools the virtual/daemontools will be pulled in which the dependencies of virtual/service-manager. If you need OpenRC, you should add it to your world file.
