I checked over the answer on stackexchange, played around with an
example of juggling file descriptors, and found this seems to work:
{ ls ${DIR} ; } 2>&1 | tee mylog
catching the output whether DIR exists or not. So I'm going to try
{ rm -rf /usr/obj/* && cd /usr/src && make obj && \
cd /usr/sr/etc && env DESTDIR=/ make distrib-dirs && \
cd /usr/src && make build ; } 2>&1 | tee /var/log/build/buildsys.log
in a script by itself now.
Sorry for talking to myself on list

Be careful when you look at conspiracy.
Arm yourself with knowledge of yourself, as well:
