I had a long list of packages to unmerge (I was removing KDE from a computer), and emerge -C was run with all the package names as arguments (and, to make sure I was not running an emerge -C for each package, I copied and pasted the package names after the emerge -C command, instead of using the little one-line bash script I mentioned in the forums). The issue is that portage is regenerating the /etc/ld.so.cache for each package which is unmerged, instead of running it once, at the end of the emerge -C job. (I just calculated that it must have spent about an hour with these regenerations) As it seems that there's no reason to enforce this, I'm suggesting the unmerging code is changed in a way it doesn't regenerate ld.so.cache if portage is running in -C mode. (The emerge code should run it once when exiting) Reproducible: Always Steps to Reproduce: 1. Create a list of packages to unmerge 2. run # emerge -C package list 3. Look at the output Expected Results: Portage should regenerate /etc/ld.so.cache only once, if it is just being executed with the -C argument.

If think this can be generalized as a request for "run-once" hook for portage and other PMs. I've always found nice how debian can run all the gconf, glib-schemas, fdo .desktop, fdo mime handling only once after installing everything. I think we should enable that somehow in Gentoo as well.
(In reply to comment #2) That soulds like bug 244518.
indeed. I'd say they are the same.
This might make calls in pkg_{pre/post}rm a bit slower but probably not enough to worry about. But fwiw, a related (not the same issue) got fixed a while ago: commit e893f4fc12eb618318b1945ce7a05a94fb1ea1b4 Author: Zac Medico <zmedico@gentoo.org> Date: Sun Apr 17 12:12:40 2022 -0700 MergeProcess: propagate mtimedb["ldpath"] to parent process (bug 836375) Use an instance of multiprocessing.Pipe to propagate mtimedb["ldpath"] from the MergeProcess child process to the parent process. This fixes env_update calls to avoid unnecessary regeneration of ld.so.cache in cases where mtimedb["ldpath"] has not changed since the last call to env_update.
