[It's not generally good policy to ask multiple questions in one email. As crazy as it sounds, you're better off sending a seperate email for each question.

If not I might have write one. :oP See the various documents on boot splash screens. "man splash" on your FreeBSD system is the best reference I know of, although a google search is likely to turn up more. I don't know of anything more advanced than that. You may have to write it ;) > Oh, and thanks for your comments/answers. One last question thought? How > do I get rid of that fragmentation crap? Just for shits and giggles.. > ;o) Just keep using your system. UFS manages fragmentation during normal usage. However, fragmentation is not what you think it is. If you tried to evaluate a UFS file system compared to Windows idea of fragmentation, it would look fragmented as hell, but UFS does this in a controlled manner that is intended to maintain high-performance, and "correcting" it would actually be counter- productive. UFS fragmentation is the act of breaking down storage units into smaller ones to accomodate files of uneven sizes, and I don't know of any way to prevent this other than deleting such files. See /usr/share/doc/papers/diskperf.ascii.gz for a more technical explanation of how things work. > > Bruce > > On Tue, 2004-06-08 at 02:09, Murray Taylor wrote: > > Fragmentation is a non-event in 99.999% of cases.
