I have the chown/chmod in a script I run to run= =20 cvs update on /usr/src and /usr/ports even. I just stick myself in the src= =20 group and then I can build ports as myself and let it use su for the instal= l=20 and config steps. > * Make /var/db/ports writable by user or set $PORT_DBDIR to a > writable location No, updating that is done via root as su, so you don't have to do this. =2D-=20 John Baldwin <jhb@FreeBSD.org> =A0<>< =A0http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =A0=3D =A0http://www.FreeBSD.org
