For example, if signature verification fails during a +sync operation, the new hardlink behavior will preserve the previous +state of the repository. + +The new behavior may conflict with configurations that restrict the +use of hardlinks, such as overlay filesystems. Therefore, users will +have to set "sync-allow-hardlinks = no" in repos.conf if they have +a configuration that restricts the use of hardlinks, but this should +not be very common: + +[DEFAULT] +sync-allow-hardlinks = no + +Note that it is possible to sync more efficiently using git [2] +instead of rsync, though git consumes an increasing amount of disk +space over time unless shallow pull is enabled via the sync-depth +option in repos.conf [3] (requires sys-apps/portage-2.3.42 or later). + +[1] https://bugs.gentoo.org/660410 sys-apps/portage: use rsync + --link-dest to implement atomic repository updates (and abort if + signature verification fails) +[2] https://wiki.gentoo.org/wiki/Portage_Security#git-mirror_repo +[3] https://bugs.gentoo.org/552814 sys-apps/portage: support shallow + git pull by setting sync-depth = 1 in repos.conf |
