Description igel 2013-01-29 20:32:26 UTC

It's best explained using virtuals, here is an example:
I have "virtual/udev gudev" in /etc/portage/package.use/udev but when I do "emerge virtual/udev" portage tells me to add gudev to the USEflags of sys-fs/udev because virtual/udev[gudev] requires sys-fs/udev[gudev]. My request is that portage automatically resolves this and installs sys-fs/udev with gudev (unless -gudev is specified for sys-fs/udev, in which case "cannot be installed on the same system" could be thrown).

Now, this is not limited to virtuals. Any time a package A is to be emerged that depends on package B with USEflag C, a (re)emerge of B[C] could be triggered.
This should be done _without_ adding anything in /etc/portage/package.use, since this file is supposed to contain user preferences. If I don't want my udev with gudev any more, then removing gudev from virtual/udev should suffice to not require gudev on sys-fs/udev in future merges.

Thanks for considering :]
