hello,

a friend of mine send me the following /etc/rc.c/ppp replacement
script. the idea is to start multiple instances of ppp at boot time
(possibly with different profiles).

i'm not sure if this is ok to commit as it is, so i decided to ask if
there is a better way to handle this.

any thoughts on the subject is very much appreciated.

thanks,
max
