These have been discussed before and I believe the intent is to add
them (they're simple fprintf wrappers, if I remember correctly), but
be aware that pam_unix.so's support for writing to the password
database assumes a certain form and will break things badly if the
user is using tcb shadow. It might also mess up the shadow file if it
depends on being able to iterate all entries in the shadow file; I'm
not sure if that works or not.

These are issues that need more discussion...
