Debian. Which probably explains this. I obviously looked for such a thing
before embarking on this, but didn't find anything. Debian uses a very
basic shell script for init within the initramfs, which does not appear to
parse out a vlan parameter.

I agree that a better approach here would be to use an existing pattern
already established in another distro. I'll look into implementing
Fedora's
solution in Debian. Consider the patch withdrawn.

Thanks,

There's no reason a more complex use case can't motivate a bigger change
in the future, but I simply don't need anything that complex.

Which is the same basic script that Ubuntu has patched to add vlan
support. It was not that hard
http://launchpadlibrarian.net/428242404/initramfs-tools_0.133ubuntu8_0.133ubuntu9.diff.gz
it may need slightly different busybox config which is enough in this
case to create vlan. ( I don't know if Debian's busybox config for
initramfs is compatible)

Full iproute2 is not needed.

Imho above is a lot more simple to add vlan support in
initramfs-tools, rather than patching klibc ipconfig. There is no vlan
syntax in ip= and imho ipconfig should only be limited to "ip="
handling.
