[PATCH 0/1] sysvinit: fix problem in switching runlevels

[Qi.Chen]

From: Chen Qi <Qi.Chen@windriver.com>

This patch has been tested with the following steps.

1. Build an image with nfs-utils and rpcbind.
2. Add to /etc/fstab an nfs mount point with the following commands.
mount -o loop tmp/deploy/images/qemux86/core-image-minimal-qemux86.ext3 root-disk-dir/
mkdir -p root-disk-dir/home/root/test
if ! grep -q 'nfs' root-disk-dir/etc/fstab; then
    echo "192.168.7.1:/home/chenqi/test /home/root/test nfs defaults 0 0" >> root-disk-dir/etc/fstab
fi
umount root-disk-dir
3. runqemu qemux86 qemuparams="-serial stdio" bootparams="console=ttyS0"
4. init 1 (Network interface down and no nfs mount point)
5. init 3 (Network interface up and nfs mount point available)
6. init 5 (Network interface up and nfs mount point available)

[PATCH 1/1] sysvinit: fix problem in switching runlevels

[Qi.Chen]

From: Chen Qi <qi.chen@windriver.com>

Previously, if we switch to runlevel 1 and then switch back to runlevel
5, the network interface will be brought down and the NFS service will
not be restarted correctly.

The problem is that the networking and rpcbind services are brought down
in runlevel 1 but not brought up in runlevel 5.

This patch fixes the above problem. It's based on the assumption that
in sysvinit-based system, runlevel 1 does not have networking support.

This patch adjusts some init script parameters used by update-rc.d. It
makes sure that networking starts before rpcbind which in turn starts
before mountnfs.sh. When switching to runlevel 0, 1 and 6, the umountnfs.sh
is run first before stopping rpcbind service, and the network is brought
down afterwards.
