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. + +2. Install sys-apps/merge-usr. + +3. Run the merge-usr script. The --dryrun option may be used to + check for error conditions before running the script for real. + +4. Switch to a merged-usr profile. + eg. eselect profile set default/linux/amd64/17.1/systemd/merged-usr + +5. Run emerge with the --newuse or --changed-use option to rebuild + any packages that have a "split-usr" USE flag. + eg. emerge -uDN @world + +For new installs, new "mergedusr" stage3 tarballs are being produced for +commonly used profiles. + +[1] https://lists.freedesktop.org/archives/systemd-devel/2022-September/048352.html |
