File system read only

["John Dean" <maillist jed id au>]

 Anyone know why a file system would be changed to read only and how it may
 have been changed.

 I'm asking, because I came home today and my file system on my fedora 2
box was mounted as read only. I had to manually run a disk check to fix some
 file system errors to get the machine to boot.

 Anyone have any idea?

 Thanks.
