I want to downgrade systemd from 207-r2 to 204 (highest stable).

I currently have virtual/udev-206-r2 installed, which prevents

OK.  So I need to downgrade virtual/udev to 200.

I thought
    emerge -1 =virtual/udev-200  =sys-apps/systemd-204
would do it.  But this failed (see below) and suggested masking
might help.

So I added package.mask/systemd, which contains
   >=virtual/udev-201
   >=sys-apps/systemd-205
and then issued the same emerge as above.
But this also failed (see below).
What incantation do I need?

Don't mask anything, just make sure that systemd (both virtual/ and
sys-apps/) is not on package.keywords. Then uninstall virtual/udev,
downgrade systemd (just "emerge sys-apps/systemd") and then emerge
again virtual/udev. The correct version should be emerged.

Nothing in the tree (AFAICS) depends on >=virtual/udev-206, so it shoud be fine.

wrong.

>=sys-apps/hwids-20130717-r1 requires >=virtual/udev-206
