As warned about previously in a news item, systemd-255 has dropped
support for split-usr systems. All Gentoo systems running systemd will
need to be migrated to merged-usr.
Migrating to merged-usr will move all data from /bin, /sbin, and /lib
into the /usr/bin and /usr/lib directories. The directories in / are
replaced with symlinks.
To facilitate this, a new set of sub-profiles has been created, and a
script is available to perform the actual migration.
To migrate a system to merged-usr, follow this procedure:
1. Ensure your system backups are up to date. Please also update
your system fully and depclean before proceeding.
2. Install sys-apps/merge-usr.
3. Run "merge-usr --dryrun" as root to check for conflicts. These will
appear with the word ERROR at the start of the line.
4. Resolve any conflicts. This may involve deleting duplicate files. If
in doubt, seek support in a Gentoo support channel.
5. Run the merge-usr script from a root shell. Avoid running it via sudo
directly to avoid locking yourself out if an unexpected error occurs.
6. Switch to a merged-usr profile.
7. Run emerge with the --newuse or --changed-use option to rebuild
any packages that have a "split-usr" USE flag.
