Point well taken, that this is common knowledge for anyone who has any familiarity with the system. I think the point being made is that if a mistake is made or an inexperienced user is at the system, there should be some failsafe to prevent the system from locking down or panic'ing. When we're talking about a floppy (or any removable media) there is a vary good chance that, the mounted file system could be removed w/o unmounting it. It would be just good practice to protect the system against that. If FreeBSD is to stay primarily a server oriented OS or a 'nitche market', than for the most part, no one cares because 99% of people who use FreeBSD know to mount / unmount the floppy (as inconvenient and un-intuitive as that may be). If FreeBSD does want more of a user base, and is going to be touted as a 'desktop operating system', then certain concessions and falsifies need to be integrated into the system, as to not drive those potential users away. That's just my opinion. -Chris > -----Original Message----- > From: Boune, Damian [SMTP:DBoune@co.napa.ca.us] > Sent: Tuesday, August 17, 1999 5:57 PM > To: freebsd-questions@FreeBSD.ORG > Subject: bug wich crashes freebsd 3.2 > > Our friend makes a good point.
