The only parts it doesn't do are the kernel itself and ports. I always do it as single user (I do a 'shutdown now' beforehand) because it replaces all the shared libs too, and that makes me nervous. I've been told this isn't necessary anymore, but I've never gotten a satisfactory explanation why not, so I feel safer that way. The make world does all the other parts (make depend, the directory tree, Make all, make install) you ought to go glance at the /usr/share/mk files and the /usr/src/Makefile itself. If you don't tell the make world otherwise, it compiles all the security in. I did this once and found myself locked out of my own machine, even tho I knew the passwords. Since I don't have any net connectivity, I feel I can get along with reduced security, so I invoke the make as: make world -DNOSECURE This doesn't remove passwords, but it does inhibit the Kerberos stuff, and the DES stuff. Passwords then are based on MD5. I usually use -DNOPROFILE also, to suppress building all the profiled libraries (saves time and diskspace, unless you need them). If you mess up on security, I saved myself once by booting 'kernel -s' so I entered single-user immediately, bypassing the password check. If I have any of this wrong, and someone sees it, I'd be happy to be corrected. > > thanks... > > Marc G.
