The bootstrap protocol is to unpack all relevant packages and then configure them. deboostrap currently deviates from the bootstrap protocol in performing a merge, but DEP17 will revert eventually. Let us assume that coreutils moves /bin/cp to /usr/bin/cp. Then a bootstrapping tool unpacks all relevant binary packages, but does not perform any kind of merging. The init-system-helpers dependency on usrmerge | usr-is-merge causes usrmerge to be installed. usrmerge.postinst runs convert-usrmerge on an unmerged tree. This will call "ldd /bin/cp", but "/bin/cp" does not exist and convert-usrmerge fails. This is bad. The patch makes usrmerge work in a scenario where cp has been moved to /usr/bin/cp already. This change is only useful very temporarily. The plan goes on to change base-files to install the aliasing symbolic links. Then, base-files will provide usr-is-merged and usrmerge will no longer be installed by bootstrapping tools. For changing base-files we need to do a coordinated upload of involved packages. In adding this change to convert-usrmerge, we reduce the packages involved and can convert coreutils at an earlier time. The change about restorecon is cautious and not strictly necessary. I do not see a scenario where this should practically make a difference. Helmut
