What if it is a rw,no_root_squash export? Or does the Debian initscript
not support remounting the nfsroot rw? Or is it a limitation of the
Linux kernel?

Okay, will do. I've enabled CONFIG_DEVFS_FS and CONFIG_DEVFS_MOUNT.

When booting with the old baseplus, I got the following messages:

INIT: version 2.78 booting

Should these concern me, or not?

I'm going to try building a new nfsroot tarball with the latest debs.
Hopefully that will do the trick.
