What's the point of the shell choice in single user mode?

I just tried it again with exactly the same results (FreeBSD-7.0 beta3):

[after pressing 4 at the Beasty menu]

Trying to mount root from ufs:/dev/ad4s2a
Enter full path name of shell or RETURN for /bin/sh:
sh: Cannot open /etc/termcap
sh: using dumb terminal settings
%fsck -p
fsck: Command not found
%mount -u /
mount: Command not found
reboot: Command not found
logout ... continues to a Login prompt.

Pressing RETURN or typing /bin/sh gets a '#' prompt and working fsck etc.

Is your /etc/termcap a symlink?

ll /etc/termcap
lrwxrwxrwx  1 root  wheel  23 Nov 15 20:27 /etc/termcap -> /usr/share/misc/termcap

Thanks, John.
