No, the idea is:
    There's this box in a corner which build on a "regular"basis:
    4-STABLE for some production servers (haven't tried upgrading those)
    5-RELEASE for my fileserver and firewall
    5-CURRENT for not critical boxes
    5.1 as an intermediate when I following some migrations since
        my COMPAQ ML370 does not always like CURRENT

I export /usr/obj, /usr/src{4,4,51,52} to the same mounts on the
system I want to upgrade. And normally I can just follow the regular
process, where I get to single mode via multi-user mode, so all IP
stuff is loaded and started.

I only seriously ran into the discussed catch when I installed a fresh
system (for some NFS performance tests) with an old 5.0-DP1 release
and wanted to upgrade that to 5.1 or 5.2.

I tried your suggestion(-p), but it still gives 'signal 12'
But perhaps my system is too botched right now.
Doing it the 'hard' way works:
    cd /usr/obj/usr/src51/src/sys/sys/GENERIC
    make install
