Message:
  • remove some obsolete firewall config stuff
  • add old-style network configuration based on nvram
  • add new rc.conf file to configure which services should be started on startup, bsd-ish behavior
  • disable firewall by default in rc.conf, remote update via ssh is now possible. port 22 is open by default on wan side
  • enable suid bit on busybox and add a "admin" user
  • ssh via root is disabled (dropbear -w)
  • default password for "admin" is "FreeWRT", as well as for root please change directly after installation
  • remove telnetd from startup, will be used only for failsafe
