I used to build world and kernel on one machine and export both /usr/src/ and /usr/obj read-only to other machines. It doesn't work anymore (this is from 'make installworld'):
===> bin/freebsd-version (install)
eval $(egrep '^(TYPE|REVISION|BRANCH)='
/usr/src/bin/freebsd-version/../../sys/conf/newvers.sh) ; if ! sed -e "
s/@@TYPE@@/${TYPE}/g; s/@@REVISION@@/${REVISION}/g; s/@@BRANCH@@/${BRANCH}/g;
" /usr/src/bin/freebsd-version/freebsd-version.sh.in >freebsd-version.sh ;
then rm -f freebsd-version.sh ; exit 1 ; fi
cannot create freebsd-version.sh: Permission denied
rm: freebsd-version.sh: Read-only file system
*** Error code 1
