Ce matin ma machine à écrire me propose une évolution de son système d’exploitation. Après lecture de quelques docs j’acquiesce et je me lance dans la mise à jour. Peut-être une fois l’étape terminée mon clavier midi collaborera ce soir enfin avec ma machine à écrire ;-)
Why the /usr Merge Makes Sense for Compatibility Reasons
This is based on the Fedora feature for the same topic, put together by Harald Hoyer and Kay Sievers. This feature has been implemented successfully in Fedora 17.
Note that this page discusses a topic that is actually independent of systemd. systemd supports both systems with split and with merged /usr, and the /usr merge also makes sense for systemd-less systems. That said we want to encourage distributions adopting systemd to also adopt the /usr merge.
What’s Being Discussed Here?
Fedora (and other distributions) have finished work on getting rid of the separation of /bin and /usr/bin, as well as /sbin and /usr/sbin, /lib and /usr/lib, and /lib64 and /usr/lib64. All files from the directories in / will be merged into their respective counterparts in /usr, and symlinks for the old directories will be created instead:
/bin → /usr/bin
/sbin → /usr/sbin
/lib → /usr/lib
/lib64 → /usr/lib64
