Some packages in Sisyphus install files both under %_prefix and outside it in subdirectories of /, e. g. in both /bin and /usr/bin, or in /sbin and /usr/sbin. Those packages must be installable into both unmerged and merged-usr hierarchies and still work correctly. Most of the packages can be adapted for use on both hierarchies, if they are rebuilt with rpm-build with this brp module, with no spec changes required. This brp module ensures that files under %buildroot/bin and %buildroot/usr/bin are a copy of each other. If one of them is a symbolic link to another, it is replaced by a copy of its target. If different files of the same type are found inside the buildroot, it fails the build. Likewise for %buildroot/sbin. This approach has the following advantages: - The resulting package can be installed on a split-usr hierarchy. We cannot use hard links, since our RPM can not auto-replace them while installing in an environment where hard link targets are to be on different storage sources (aka "split-usr"). - Most of packages in the repo should be installed in both hierarchies as is or after rebuild. The single worst disadvantage is disk space requirements: we store 2 copies in the cpio of product rpms and 2 copies while installed on an unmerged-usr hierarchy. We hope that this is not too bad: the copied files themselves are not that big, the cpio in a package file is compressed, and the eventual upgrade of filesystem < 3 is much less likely to hit disk space limits. As for files in /lib*, it is unlikely for packages in the repository to depend on their particular location, so there is no need to put links or copies both outside %_prefix and in %_prefix; all the packages with file conflicts exclusive to merged-usr setups are fixed already. This module can be safely disabled or removed when we eventually drop support for unmerged-usr hierarchies. Link: https://altlinux.org/Usrmerge
