Re: I/O operations

Ok, how about this:   completely suspending all I/O can be done.   two
possible answer:

1.   suspension on root device:   reboot using a LiveCD, and mount the
rootfs as readonly.
2.   suspension on non-root device:   unmount it first - after
removing all dependencies, remount as readonly.   now your device will
suspend all write but not read.
