Good idea, thanks. I'm not 100% convinced it is worth a useflag (instead of |
| 7 |
e.g. a make.defaults variable that one can override in make.conf), but why |
| 8 |
not. |

Your patchset seems to be missing some ebuilds in that regard: expat and |
| 16 |
sys-freebsd/* come to mind. |

It should be noted that, unless I missed something, the default settings |
| 24 |
will *not anymore* allow sep-usr after this patchset (sep-usr useflag will |
| 25 |
be disabled). This should be advertised more (a news item?) or simply |
| 26 |
sep-usr added to make.defaults. The latter will also enable busybox's |
| 27 |
sep-usr support. |
