for some DES passwords
crypt(real_password, salt)
is equal to
crypt("", salt);
It means that this user (and not only he) can login without
entering password at all, just pressing Return.
So if empty password entered and crypted password is not empty,
invalidate any crypt result by assigning ":"
Otherwise, when pressing the INT ke at the password prompt, the password
will be displayed. Now login will be killed.
Probably the same will have to be done for the LOGIN_CAP_AUTH case.
I have not done that.

string literals for the filesystem names. NetBSD's MOUNT_UFS is
"ffs", so using a literal "ufs" gives wrong results, but this is
unimportant, especially for bootstrapping.

either set of tools. The only difference is where the pre-processor

the tree does not compile well if you do not have matching header files
installed. Half-baked -I directives don't cover enough of the cases.)
