This confirms that I'm understanding somewhat more now what is what about that
in UPDATING.

So since my buildserver is running current
(although an old one: FreeBSD 5.2-CURRENT #25: Mon Dec 22)
it builds, when building 5.1, the installation toolset to be used on 5.2.
And those tools cannot be used on 5.1 due to the missing systemcall.
So what I/it would need then, is to build 5.1 compatible installtools on
a 5.2 running system???

For the time being I'll start packing, counting my beans, reading UPDATINGS,
ski down some slope. And refigure the issue after I get back.

Thanx for all the patience Des,
