Important:
- don't set any flags automatically; always follow user
  suggestion (multicast, arp)
- merge baggins changes in atm-rc (added support for RFC1483/2684 Bridged
  protocol)
- killproc() sucks and has no consistency, error reporting
  you'll never know which side of PROCNAME you should add the --waitforname or -SIGNAL args
  because if you put -SIGNAL at wrong side of PROGNAME it will enter infinitive loop:
    killproc -TERM --waitforname slapd --waitfortime 300 slapd
  if you put --waitforname at wrong side, it will just ignore them:
    killproc slapd -TERM --waitforname slapd --waitfortime 300
  while correct would be:
    killproc --waitforname slapd --waitfortime 300 slapd -TERM
- switch to use __umount_*loop instead of own umount loop when stopping system
- rc-scripts won't work if /dev/console is invalid (for example I made typo when configuring serial
  console, console=ttys1,... instead of console=ttyS1) - rc.d/rc uses /dev/console a lot

Other:
- maybe merge ATM rc scripts

We are waiting for suggestions.
