Mini Shell

Documentation:

- Update the docs
  - Update README
  - Update INSTALL
  - Merge INSTALL & README.privsep

- Install FAQ?

- General FAQ on S/Key, TIS, RSA, RSA2, DSA, etc and suggestions on when it
  would be best to use them.

- Create a Documentation/ directory?

Programming:

- Grep for 'XXX' comments and fix

- Link order is incorrect for some systems using Kerberos 4 and AFS. Result
  is multiple inclusion of DES symbols. Holger Trapp
  <holger.trapp@hrz.tu-chemnitz.de> reports that changing the configure
  generated link order from:
	-lresolv -lkrb -lz -lnsl  -lutil -lkafs -lkrb -ldes -lcrypto
  to:
	-lresolv -lkrb -lz -lnsl  -lutil -lcrypto -lkafs -lkrb -ldes
  fixing the problem.

- Write a test program that calls stat() to search for EGD/PRNGd socket
  rather than use the (non-portable) "test -S".

- More platforms for for setproctitle() emulation (testing needed)

- Improve PAM ChallengeResponseAuthentication
 - Informational messages
 - Use different PAM service name for kbdint vs regular auth (suggest from
   Solar Designer)
 - Ability to select which ChallengeResponseAuthentications may be used
   and order to try them in e.g. "ChallengeResponseAuthentication pam"

- Complete Tru64 SIA support
 - It looks like we could merge it into the password auth code to cut down
   on diff size. Maybe PAM password auth too?

- Finish integrating kernel-level auditing code for IRIX and SOLARIS
  (Gilbert.r.loomis@saic.com)

- 64-bit builds on HP-UX 11.X (stevesk@pobox.com):
  - utmp/wtmp get corrupted (something in loginrec?)
  - can't build with PAM (no 64-bit libpam yet)

Clean up configure/makefiles:
- Clean up configure.ac - There are a few double #defined variables
  left to do.  HAVE_LOGIN is one of them.  Consider NOT looking for
  information in wtmpx or utmpx or any of that stuff if it's not detected
  from the start

- Replace the whole u_intXX_t evilness in acconfig.h with something better???
 - Do it in configure.ac

- Consider splitting the u_intXX_t test for sys/bitype.h  into separate test
  to allow people to (right/wrongfully) link against Bind directly.

- Consider splitting configure.ac into separate files which do logically
  similar tests. E.g move all the type detection stuff into one file,
  entropy related stuff into another.

Packaging:
- HP-UX: Provide DEPOT package scripts.

PrivSep Issues:
- PAM
  + See above PAM notes
- AIX
  + usrinfo() does not set TTY, but only required for legacy systems.  Works
    with PrivSep.
- OSF
  + SIA is broken
- Cygwin
  + Privsep for Pre-auth only (no fd passing)
