This is also nowhere documented: I've been using LVM2 as a root filesystem for years without incident, so of course I thought it was meant to work. (So much for backing up the whole system from snapshots, too...) I must admit I can't see what's so special about the root filesystem. >From the kernel's POV it's just another vfsmnt: you can even unmount it if you have no open sessions and you have a rootfs still mounted under it.

I'd vaguely guess that only snapshot support is broken? -- `In typical emacs fashion, it is both absurdly ornate and still not really what one wanted.' --- jdev _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
