It's impossible to update the rsync package in portage. Because "rsync" is
interpreted as a command even though a -u was passed before rsync.
Steps to Reproduce:
1. portage -pu rsync
or protage -u rsync
[root@taylor] /home/matze > emerge -pu rsync
emerge: the "sync" action does not support "--pretend."
[root@taylor] /home/matze > emerge -u rsync
>>> starting rsync with rsync://rsync.gentoo.org/gentoo-portage...
... (updated my portage tree)
The correct result would have been ro update the rsync package
try "emerge net-misc/rsync"
