No, but it may be necessary to run "make includes" before (see recent threads, both in this list and in hackers). You may also want to remake the kernel and install it, if you're using make world to upgrade your version of FreeBSD. > > 3.

It shouldn't, but to be on the safe side, back it up. BTW, if you make world with new sources that have changes in some files in /etc, you'll have to merge /usr/src/etc and /etc yourself. > > 4.

Sure, go to the relevant directory in the /usr/src hierarchy and do a make and make install in that directory. > > Thanks for your help in answering these. > > Donald Burr <dburr@POBoxes.com> - Ask me for my PGP key | PGP: Your > WWW HomePage: http://DonaldBurr.base.org/ ICQ #1347455 | right to > Address: P.O.
