Another interesting e.g. --
emerge --autounmask=y --autounmask-backtrack=y --backtrack=300 -pv --getbinpkg --oneshot app-emulation/wine-vanilla
These are the packages that would be merged, in order:
Calculating dependencies ... done!
The following USE changes are necessary to proceed:
(see "package.use" in the portage(5) man page for more details)
# required by app-emulation/wine-vanilla (argument)
>=app-emulation/wine-vanilla-6.0.2 -abi_x86_32
app-emulation/wine-vanilla abi_x86_32 is set in my package.use on purpose. and autounmask suggests that I has to be removed.

I created a USE flag dep conflict today: www-servers/apache-2.4.4-r3 -threads dev-lang/php-* apache2 threads while php[apache2] depends on apache[threads=]. With --autounmask y the output is: ===================================================================== These are the packages that would be merged, in order: Calculating dependencies... done!

One of the following packages is required to complete your request: - www-servers/apache-2.4.4-r3::gentoo (Change USE: +threads) - dev-lang/php-5.4.13::gentoo (Change USE: -threads) (dependency required by "dev-lang/php-5.4.13" [installed]) (dependency required by "www-apps/gallery-3.0.7" [installed]) (dependency required by "@selected" [set]) (dependency required by "@world" [argument]) ===================================================================== Emerge is obviously aware of the fact that switching to apache[threads] and php[-threads] are two correct ways to solving the conflict. I propose that --autounmask=y too offers both/all known alternatives, not just one. Emerge's behavior with --autounmask-write=y would be left unchanged, of course. Reproducible: Always
