Hi all, in for example
http://security.freebsd.org/advisories/FreeBSD-SA-10:08.bzip2.asc :
# cd /usr/src
# patch < /path/to/patch
# cd /usr/src/lib/libbz2
# make obj && make depend && make && make install
I assume I can't do this safely if my /usr/src tree has been updated
since my last make world?
