 |
|
Hello,
I have all my Gentoo with OpenRC.
With 23.0 profile i switched on the split-usr of course.
The "standard" profile looks like, for OpenRC, merged-usr.
Can i keep the split-usr all the time or in next months/years OpenRC must migrate to merged-usr and split-usr won't be supported ?

| I have not seen any announcement indicating that split-usr will be removed from openrc. Therefore, as with all projects, it will be supported until the people who work on the project choose not to support it anymore. That will most likely be when supporting it becomes too much trouble relative to the value that they gain from that support. We have already seen early cases of things breaking due to merged-usr assumptions, so I would not be surprised if additional upstream projects over time begin assuming "All the world is merged-usr" (even if almost none of it is VAX) and break on a split-usr setup. If too many of those break, the developers supporting split-usr might give up and abandon it. Absent specific statements from the relevant developers, I choose not to worry yet. There will always be the chance to migrate later, if that becomes necessary. The migration procedure for merged-usr looks fairly easy, so I don't expect to find myself stuck with no path forward, even if merged-usr becomes mandatory. |

I think open-rc split-user days are numbered.
The 23.0/split-user profiles exist but there are no split-user stage 3 tarballs to download.
We need the inverse of
| Code: | * sys-apps/merge-usr
Available versions: 6 {PYTHON_SINGLE_TARGET="python3_10 python3_11 python3_12"}
Homepage: https://github.com/floppym/merge-usr
Description: Script to migrate from split-usr to merged-usr |
I found a Nov-23 17.1 stage3 for a new install a week or so ago, as I don't want a mix and couldn't face writing sys-apps/split-usr :)

There still is an amd64 split-usr stage3 under the advanced section. However, this is the only one currently being produced.
Others could be produced if there was demand. I'm sure anyone could create them using catalyst with minor modifications to the Gentoo recipes for alternate arches.
Edit: seems arm64 also has split-usr |

All people who have /usr on an extra partition cannot switch to merged-usr unless other requirements are met (-> https://wiki.gentoo.org/wiki/Early_Userspace_Mounting ). However, if /usr is a normal directory in your root partition, there is no reason not to migrate to merged-usr. I also have an OpenRC system and migrated to merged-usr the day after I switched to 23.0 profiles: https://wiki.gentoo.org/wiki/Merge-usr =>
| Code: | # emerge -uNDv @world
# emerge -1v merge-usr
# merge-usr --dryrun
# merge-usr
# eselect profile set X
# emerge -uNDv @world |
(-> 17 packages updated)

OK, so the best thing to do is migrate to merged-usr with OpenRC (profile without "split-usr") when i have the time. (i don't have /usr on specific part)
No stress when the split-usr will be unsupported (when it will be..)
But indeed, i didn't see official news about that, but see "split-usr" explicit in the profile name trough me, maybe, will be unsupported soon
