Do you have /etc/passwd set up correctly? I guess perhaps the code should
be a bit more lenient - if you're specifying a username on the commandline
(ie user at host), then the username from the system isn't actually required.
I assume you're specifying a username, otherwise it should fail in
cli-runopts.c with "Unknown own user"?

A workaround for the moment is to replace

dropbear_exit("Failed to get homedir");

with

dropbear_log(LOG_WARNING, "Warning: Failed to determine homedir");
ask_to_confirm(keyblob, keybloblen);
goto out;

in cli-kex.c

Let me know how that goes.

Cheers,
Matt
