Built with glibc 2.1.3. configure command line:

	# CC=gcc CFLAGS='-Os' \
	./configure \
        --disable-zlib --disable-lastlog \
        --disable-utmp --disable-utmpx --disable-wtmp --disable-wtmpx \
        --disable-shadow \
        --disable-libutil \
        --disable-openpty

options.h was modified (see options.h.diff), and:

+ X11 forwarding disabled
+ encription 3DES and BLOWFISH supported, AES128 and TWOFISH128 disabled
+ integrity SHA1 supported, MD5 disabled
+ DSS, RSA and password authentication supported (password and RSA verified)
+ MOTD disabled
+ SFTP disabled
+ this is a multi-purpose binary (DROPBEAR_MULTI enabled) with dropbear and
  dropbearkey executables combined in dropbearmulti; dropbear and dropbearkey
  are actually symbolic links pointing to dropbearmulti


The ELF executable (dropbearmulti) is sstripped and upx-ed.

There are pre-dropbear.ini and a post-dropbear.ini scripts. Both may be
required, for now.

This is what pre-dropbear.ini does:

  + creates a real home directory /root for user root
  + modifies the /etc/passwd file to reflect the 'root' user's new home
    directory
  + creates the .ssh subdirectory under /root; that's where the
    authorized_keys file will be copied to (put your own authorized_keys in
    the /packages directory on the floppy, and it will be copied to the right
    place)
  + finaly copies the authorized_keys file to the right place

Note: you'll need to edit the script and set the DES_PWD variable to something
      sensible, if you want to use password authentication.

Note: you need a VFAT formated floppy for this to work. The file
      authorized_keys does not follow the brain dead 8.3 doz convention;
      of course you can modify the script to do otherwise.

Warning: if you want to modify the script, notepad won't work;
         you'll probably need a real word processor to modify the 30 lines
         long script ;-) 

post-dropbear.ini will copy the DSS and RSA host keys it finds in the
/packages directory on the floppy to the right place. The keys on the floppy
should be named drop_dss.key and/or drop_rsa.key. Any host keys not found in
/packaces on the floppy will be generated at boot.

Note: starting with v0.38, the host key files are relocated to the
      /etc/dropbear directory (from earlier /etc).

Tips: mount the floppy after the first boot and copy the generated host keys
      to it.

Should you have any comments and/or questions, throw them at me and I'll try
to answer to the best of my abilities ;-)

Enjoy,
