NOTICE:
The FreeBSD world/kernel build process seems to dislike having its sources mounted via smbfs. If you witness strange errors or compiler crashes, and they're not due to the samba connection timing out, then you may have to copy the sources locally before building. A pain, I know.
Commands:
mkdir /mnt/src mount -t smbfs //guest@server/src /mnt/src mount -t nullfs /mnt/src/FreeBSD/RELENG_8_0/src /usr/src mount -t nullfs /mnt/src/FreeBSD/ports /usr/ports mkdir -p /var/ports/distfiles
fstab:
//guest@alba/src /mnt/src smbfs ro 0 0 /mnt/src/FreeBSD/RELENG_8_0/src /usr/src nullfs ro 0 0 /mnt/src/FreeBSD/ports /usr/ports nullfs ro 0 0
Ports really loves building things in-tree. Doesn't really work with a read-only ports tree.
make.conf:
# Read-only ports tree DISTDIR=/var/ports/distfiles PACKAGES=/var/ports/packages WRKDIRPREFIX=/usr/obj
Workdir will be ${WRDKIRPREFIX}/${PWD}/work, so /usr/obj/usr/ports/sysutils/screen/work/ for sysutils/screen. Won't interfere with buildworld/buildkernel this way.
