  You should put your SSH keys in "/mnt/kd/ssh_keys".  SSH will build
the authorized_keys file on boot or init.

  The keydisk is simply a place for persistent storage, specific to
astlinux...   The various init scripts check specific locations for
overrides, includes, etc.

  Unionfs will be used in AstLinux 0.5 and later to accomplish this.

  None of these questions are specific to AstLinux, but I'll try to
answer what I can.  Linksys/Sipura devices can also TFTP to the server
provided via DHCP options (option 66).

  Yes.  Perl is a bit heavy, but miniperl is included for simple scripts.

  That's just it.  Make some simple bash/sed/etc scripts.

  I don't really do XML, I wouldn't know.

  Use a different DHCP server?
