[gentoo-user] split-usr

[William Kenworthy]

Some years back I did the usr-merge and my laptop has continued on more
or less ok.

Now, I suddenly have a number of packages failing to build with internal
collisions as they try and install (for example) a binary into /bin and
/usr/bin and collide.  "emerge --info" is showing the split-usr flag
enabled on my profile (5):

  [5]   default/linux/amd64/17.1/desktop (stable)
  [6]   default/linux/amd64/17.1/desktop/gnome (stable)
  [7]   default/linux/amd64/17.1/desktop/gnome/systemd (stable)
  [8]   default/linux/amd64/17.1/desktop/gnome/systemd/merged-usr (stable)
  [9]   default/linux/amd64/17.1/desktop/plasma (stable)
  [10]  default/linux/amd64/17.1/desktop/plasma/systemd (stable)
  [11]  default/linux/amd64/17.1/desktop/plasma/systemd/merged-usr (stable)
  [12]  default/linux/amd64/17.1/desktop/systemd (stable)
  [13]  default/linux/amd64/17.1/desktop/systemd/merged-usr (stable)

So which profile should I use for an XFCE4 desktop.  This laptop is
openrc and predates the devils spawn (systemd) and I dont use gnome or
plasma?

[5] is what I have been using here for years and I am also an
XFCE/openrc addict. I recently switched to a merged
desktop[5]/hardened[3] profile. split-usr is set but it's the first time
I notice it and I don't know what the usr-merge is. No issues with
merges. Not much help for your problem, I know.

Directories like /bin, /sbin, /lib* will soon/eventually migrate to /usr and
merge with their synonyms there. This has already taken place on systemd and
a migration is on the cards for openrc. The baselayout package will change
among others and I expect some migration script would be provided. Otherwise
it would be a manual job of shifting directories around. Leaving the split-
usr flag set is what should be used with the stable packages at the moment and
it won't cause any problems.

Hello William,

from the profiles listed you probably go with the plain desktop profile
[5] at best.

In the 23.0 profiles the /usr merge will be properly addressed, until
then you'll need to do the adjustments in your /etc/portage/.

To see what is needed, you can check the actual changes which the
merged-usr profiles introduce in ::gentoo repository:

profiles/features/merged-usr/

From what you're describing I think you you're not properly masking the
split-usr USE flag, i.e. check especially use.force and use.mask.

Cheers
Felix
