https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225423 --- Comment #19 from Kirk McKusick <mckusick@FreeBSD.org> --- (In reply to Konstantin Belousov from comment #18) If you unmount /dev you lose your console, /dev/null, /dev/zero, /dev/random, etc. A system without these fails to work pretty quickly (as I discovered when I created a jail and forgot to put a /dev in it). I expect a system running with any local filesystem (e.g., UFS, ZFS, ext2fs) would crash and burn pretty quickly if its access to disk was removed. Of course, in insecure mode (which is what we run in by default) we allow root to scribble all over kernel memory through /dev/kmem so unmounting /dev is no worse than that. -- You are receiving this mail because: You are the assignee for the bug.
