"emerge --sync" launches rsync with the unsuported argument "--filter" rsync exits with a syntax error and the message: "rsync: --filter=H_**/files/digest-*: unknown option" emerge takes that personally and exits, too. Reproducible: Always Steps to Reproduce: 1. Get a system with sys-apps/portage-2.1.2.2 and net-misc/rsync-2.6.0-r6 2. Launch "emerge --sync" Actual Results: emerge exits without rsyncing anything; rsync says: rsync: --filter=H_**/files/digest-*: unknown option Expected Results: Package database being rsynced. I can not give the complete portage error message, because I already masked =sys-apps/portage-2.1.2.2 locally and downgraded to 2.1.2-r9 and later to 2.1.1-r2 as suggested by portage after emerge --sync . Now I am able to update rsync, but I won't, for that could mess up things again. Maybe updating rsync would have been a better solution in the first place, but I did not think of that at that time. To prevent other people from having this trouble, somebody could make portage-2.1.2.2 depend on a version of rsync that supports --filter .
