As you've figured out the hard way: nope, it didn't write anything.
It figured a bogus superblock, and it wants to make sure to not
accidentally clobbering anything valid, thus it didn't write it out.

(The initial bootblocks have been written with libdisk from inside
sysinstall.  That's why they even were on the disk... libdisk used to
have a bug where it left out a few numbers disklabel(8) requires.)

Declare the terminal as `local'.  (stty clocal or something like this,
i think at least kermit should be able to handle this.)
