Hi,
As you may have noticed Factory activated the UsrMerge last week. Tumbleweed tests in openQA look good, only a non-usrmerge related bug prevents the release. I haven't received a lot of feedback from the call for testing so I hope that means the migration works really well :-)
Plain vanilla EXT4 system here. No problems, except for a few download timeouts. All of those downloaded fine with retry. 3000+ new files. Magic! Thank you Carl
Therefore *your next dup will automatically and live migrate your installation* to UsrMerge. Make sure to actually use "dup" and not just "up".
Means everything in /bin, /sbin, /lib and /lib64 will be merged into their counterparts in /usr, then replacing those directories with symlinks to /usr. After the migration packages that have compat symlinks like eg /bin/foo -> /usr/bin/foo will no longer be installable as they conflict with themselves. All packages in the distro have been fixed though.
Due to the full rebuild and activation of gcc11 as default compiler the next snapshot will be a big one, so make sure to have sufficient disk space.
If you are not on btrfs with snapshots and are nervous to break the system you may want to make sure eg busybox-static is installed. So if thing unexpectedly go wrong you have the tools to complete the usrmerge manually. There is no way back.
