dash is be default omited in f17, but we use -o in command line so our omit
modules list will overwrite the system configs, so dash will be installed to
initramfs.
Here avoid install dash by adding it to the '-o' list
Also remove dash dependency from rpm spec

Update: error out vlan over bridge case
This patch adds support for vlan tagged bonding,
in theory, we could support other complex setup as well,
in practice, this is not easy, so just support vlan
tagged bonding, which is the one we support in RHEL6.
Note, this patch depends on the dracut patch:

BZ: 822701
This patch implements basic software iscsi dump support. Complex iscsi
setups like ibft etc might not work.
iscsi self configuration logic is currenlty part of kdump module. At some
point of time I would like to see it in dracut iscsi module instead of
kdump module when iscsi and other subsystems become self configuration aware
for general boot.
This patch will require work for complex setups. Some of them are.
- IPV6 support
- IBFT support
- Parsing some more advanced parameters and passing to netroot option.
