My apologies if this is well-known but I've fixed 2 ebuilds this week that silently failed because dosym or dobin failed and the only sign of failure was buried in the /var/log/portage/foo.log file. Wouldn't it be better if dobin and friends just died on failure? Alternatively, the ebuild could specify something like: dosym foo bar || die FWIW: the bugs where #223491, #224277.
Please discuss this kind of thing on the gentoo-dev@ mailing list. Bugzilla gets kind of messy when it's used as a message board. :)
Reopen, to close properly.
