Apart from the obvious benefit of making things go slightly faster, reinstalling the system will touch a lot of important system files, all the standard system binaries, libraries, include files and so on. Changing these on a running system (particularly if you have active users on the system at the time) is asking for trouble. Another method is to compile the system in multi-user mode, and then drop into single user mode for the installation. If you would like to do it this way, simply hold off on the following steps until the build has completed. You can postpone dropping to single user mode until you have to installkernel or installworld. As the superuser, you can execute: # shutdown now from a running system, which will drop it to single user mode. --=20 Gerard gerard@seibercom.net The greatest productive force is human selfishness.
