Here is the deal. Since early March, google chrome precompiled images dropped 32-bit on Linux (and platforms too). Ebuild in portage that is: =www-client/google-chrome-49.0.2623.87_p1 has only ~amd64 keywords as expected. Now, if I set stable x86 chroot and attempt to merge this version of ebuild, portage suggest to add keywords with --auto-unmask. It may be easily overlooked and any user can trust portage and add keywords, which leads to breakage. Reproducible: Always Steps to Reproduce: 1. create stable x86 chroot (or use such box) 2. emerge =www-client/google-chrome-49.0.2623.87_p1 -av 3. notice a message about adding keywords 4. hit "yes" 5. notice an expected failure. Actual Results: oleg2 / # emerge =www-client/google-chrome-49.0.2623.87_p1 -av [ebuild N *] www-client/google-chrome-49.0.2623.87_p1::gentoo USE="plugins" LINGUAS="am ar bg bn ca cs da de el en_GB es es_LA et fa fake_bidi fi fil fr gu he hi hr hu id it ja kn ko lt lv ml mr ms nb nl pl pt_BR pt_PT ro ru sk sl sr sv sw ta te th tr uk vi zh_CN zh_TW" 0 KiB Total: 127 packages (125 new, 2 in new slots), Size of downloads: 232,134 KiB The following keyword changes are necessary to proceed: (see "package.accept_keywords" in the portage(5) man page for more details) # required by google-chrome (argument) =www-client/google-chrome-49.0.2623.87_p1 ** The following license changes are necessary to proceed: (see "package.license" in the portage(5) man page for more details) # required by google-chrome (argument) >=www-client/google-chrome-49.0.2623.87_p1 google-chrome NOTE: The --autounmask-keep-masks option will prevent emerge from creating package.unmask or ** keyword changes.

How about if we set REQUIRED_USE="ABI_X86_64" in the google-chrome ebuilds? If we do that, then it will provide some useful information to package managers, since it will make it impossible to install unless the profile enables ABI_X86_64.
added in ebuild locally. that seems working: oleg2 / # emerge =www-client/google-chrome-49.0.2623.87_p1 -av * IMPORTANT: 3 news items need reading for repository 'gentoo'. * Use eselect news read to view new items.

however it may rise another questions from users?
(In reply to Oleg from comment #3) > however it may rise another questions from users? Thanks for testing. I think the resulting error message is intuitive enough, but that's just me.
I guess that will work, at least until someone decides that portage should start automatically unmasking USE flags as well.
