I tried to merge systemd with enabled usrmerge flag. It fails with: rm: cannot remove '/var/tmp/portage/sys-apps/systemd-236/image/lib/udev/hwdb.d': No such file or directory The build contains this lines: === rm -r "${ED%/}"/lib/udev/hwdb.d || die if ! use usrmerge; then # Avoid breaking boot/reboot dosym ../../../lib/systemd/systemd /usr/lib/systemd/systemd dosym ../../../lib/systemd/systemd-shutdown /usr/lib/systemd/systemd-shutdown fi === If usrmerge is set, the path of hwdb.d should be changed from "${ED%/}"/lib/udev/hwdb.d to "${ED%/}"/usr/lib/udev/hwdb.d Here the output of the lookup for that file name: # find /var/tmp/portage/sys-apps/systemd-236/ -name "hwdb.d" /var/tmp/portage/sys-apps/systemd-236/image/usr/lib/udev/hwdb.d /var/tmp/portage/sys-apps/systemd-236/image/etc/udev/hwdb.d
It is not really part of this issue but as a side note (as it is realted to usrmerge USE flag): This version of systemd introduced a static resolv.conf file for systemd-resolved and all the documentation states that the path of the file is /usr/lib/systemd/resolv.conf. So, if usrmerge is not enabled, shouldn't we also add a symlink for that file? e.g. dosym ../../../lib/systemd/resolv.conf /usr/lib/systemd/resolv.conf

Thanks for testing. I added a note that this USE flag is experimental. You should only enable it if you have already taken steps to merge /bin, /sbin, and /lib into /usr/bin, /usr/sbin, and /usr/lib.
Thanks for fixing. Is there any semi-official documentation how the merge should be done the "right" way?
What about "reverse usrmerge", that is: /usr -> . ... so everything from /usr ends up in / itself (shorter path)? Should that work? (I've not tried 236 yet to see if it does.) Duncan
(In reply to Duncan from comment #5) > What about "reverse usrmerge", that is: > > /usr -> . FWIW after merge with USE=usrmerge now... It seems to "just work". Thanks. A bit simpler now. =:^) Duncan
What about the ones that do not use usrmerge and wants to use the symbolic link to /usr/lib/systemd/resolv.conf as stated in the official documentation? Shouldn't there a line similar to dosym ../../../lib/systemd/resolv.conf /usr/lib/systemd/resolv.conf in the ebuild (if ! use usrmerge, similar to "avoid breaking boot/reboot)? See also Comment 1
