I have a problem booting with ro nfs root fs. I initialize network and mount nfs using an initrd, then pivot_root into nfs mountpoint: ... mount -n -t devfs none /new_root/dev cd /new_root # making sure we dont keep /dev busy exec <dev/console >dev/console 2>&1 pivot_root . old_root ... exec \ chroot . \ sh -c \ 'umount -n /old_root; exec /bin/env - $INIT' I removed "mount -n -t devfs" line and now "exec >dev/console" fails because /new_root is ro-mounted nfs. ro-mounted local fs (reiser3) works fine. Shall I jump thru the hoops, mount a ramfs on top of new_root/dev, populate it with device nodes, etc? I don't want to do this, I want to hand a 'clean' state to secondary $INIT. I can close all descriptors (exec <&- >&- 2>&-) before I exec $INIT, and have $INIT deal with that. This avoid the problem of >/dev/console. But I lose the ability to boot with INIT=/bin/sh then. sh doesn't expect to have stdio closed at startup. Not good. What is a 'right thing' to do in this situation? -- vda ^ permalink raw reply [flat|nested] 4+ messages in thread

It exists, but either my Mozilla or squid does not like it. Wget works. -- vda ^ permalink raw reply [flat|nested] 4+ messages in thread
