https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225423 --- 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/rando= m, etc. A system without these fails to work pretty quickly (as I discovered w= hen 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 pre= tty quickly if its access to disk was removed. Of course, in insecure mode (whi= ch is what we run in by default) we allow root to scribble all over kernel mem= ory through /dev/kmem so unmounting /dev is no worse than that. --=20 You are receiving this mail because: You are the assignee for the bug.=
