otis@b14:/usr/src % make WITHOUT_CLEAN=1 WITH_META_MODE=1 buildworld-jobs buildkernel-jobs
make: "/usr/src/share/mk/jobs.mk" line 45:
@ 1730276561 [2024-10-30 09:22:41] Start buildworld-jobs buildkernel-jobs
tee: /usr/buildworld.log: Permission denied

JOB_LOGDIR seems to need to be set to a directory writable by non-root user in this case
or it defaults to ${SRCTOP}/..
