Does the system panic? Looking at ffs_unmount(), defined by MFS for MFS unmounts, it calls ffs_flusfiles(). My question is, why flush files in an MFS filesystem in the first place? They'll be gone once the MFS filesystem is unmounted anyway. Mind you, I haven't seriously considered the possibility of an MFS filesystem being union mounted on top of some other filesystem like UFS or NFS. Even then changes made to existing files would be written to the MFS filesystem and be lost once the filesystem has been unmounted, so it may not be anything to worry about. Since I don't fully understand all of the ramifications of what I'm suggesting, maybe one of the FreeBSD wizards might want to clue me in to what's really going on under the covers.
