In the emerge man page, in the CONFIURATION FILES section, there is an error in the example command to search for config files protected as described in that CONFIGURATION FILES section. i.e. the statement: To find files that need to be updated in /etc, type find /etc -iname ´. cfg????_*´. should read: To find files that need to be updated in /etc, type find /etc -iname ´._cfg????_*´. It seems somehow the first underscore has been replaced with two spaces(?). A copy paste from the man page to a terminal failed, and the command needed to be edited to my suggested replacement in order to actually find a protected file.
Correction the command should actually be: find /etc -iname '._cfg????_*' i.e. the quotes should be apostrophes rather than closing (single) quotes.
Thanks, this is fixed in git: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=bf892931fa344f89d51d038296ca7e374ce3b30f
This is fixed in 2.1.13.7 and 2.2.0_alpha196.
