Thanks for the sysinst testing/reading information! As a quick test I tried
NetBSD 4.0.1 sysinst and current sysinst.

Differences are that NetBSD 4.0.1 installer executes .profile file, but
complains following:

mount_ffs: realpath /kern/rootdev: bad file descriptor
cp: /tmp/.root_writable: read-only file system

and then it proceeds to ask keyboard map.

Current installer just complains about unterminated quoted string and
drops to sh prompt.

I copied and checked .profile files from both installers and they're identical.
so there seems to be some odd thing that causes this issue.
