Problem using mergemaster for 10-alpha

[Shane Ambler]

I have setup a few machines in the past from CD installer and my current
machine started with CD install and was then updated from source.
Currently my machine runs 9.1-RELEASE-p3

Yesterday I started to setup a clean 10.0 install onto a new drive that
I can boot from to test ports building with, but had trouble running
mergemaster to get the config files into place. I manually copied the
/etc files from /var/tmp/temproot to get the system running.

The steps I used are based on the handbook upgrade steps but I don't
see any variations to do a clean install from source (I created empty
src.conf and make.conf to prevent using my current files) -

setenv TOPDIR ~/Projects/f10-test
setenv TMPTESTROOT /mnt
setenv MAKEOBJDIRPREFIX ${TOPDIR}/obj
cd ${TOPDIR}
svn co svn://svn0.us-west.FreeBSD.org/base/head src
touch make.conf
touch src.conf
setenv __MAKE_CONF ${TOPDIR}/make.conf
setenv SRCCONF ${TOPDIR}/src.conf
cd ${TOPDIR}/src
make -j4 buildworld
make -j4 buildkernel
mount /dev/da4p3 ${TMPTESTROOT}
make installkernel DESTDIR=${TMPTESTROOT}
mergemaster -p -a -m ${TOPDIR}/src -D ${TMPTESTROOT}
make installworld DESTDIR=${TMPTESTROOT}
mergemaster -a -m ${TOPDIR}/src -D ${TMPTESTROOT}



When using mergemaster with -a I get the following error


*** Creating the temporary root environment in /var/tmp/temproot
