virtual/dev-manager provides a wide choice of device managers, from udev to freebsd-sbin. However it doesn't cover for situations, when you aren't using any of them, i.e. by populating /dev using the DEVTMPFS / DEVTMPFS_MOUNT kernel options. Reproducible: Always Steps to Reproduce: 1. Unmerge current device manager. 2. Try to update @world. Actual Results: virtual/dev-manager is required by gentoo-sources and must be satisfied. Expected Results: I was expecting to either disable the need for virtual/dev-manager by a USE flag, either to install a dummy package to satisfy it. I'm thinking a dummy package saying "I have a dev-manager already", or multiple specific dummy packages, like "sys-fs/devtmpfs", etc, would be the best way to resolve this problem. I'm using a workaround, forcing sys-fs/static-dev to merge. This is not a good approach, as DEVTMPFS and sys-fs/static-dev are actually in conflict.
