They could use a complete rewriting, IMHO. I might be one of the guilty ones :) but i have to say, they seem to work fine on 3.1, 3.3 and even when i tried them on 4.2 they had no problem (except some glitches with mount_null which at least in 3.1 did not handle too well mmap calls as used by "cp"). In order to create a shared readonly root partition I use a script which is available at http://www.iet.unipi.it/~luigi/clone_root.010401 and basically nothing else. The modified copies of files which have to replace the original ones in the root partition are taken from /conf/${IP} or /conf/${SUBNET} or /conf, where $IP and $SUBNET are the IP address and the local broadcast address of the first configured network interface. The code in /etc/rc.diskless1 tries to find the longest match from the above. This lets you centralize the configurations, and yet have separate configuration files. It helps a lot to have not just variable assignments in /etc/rc.conf (typically a "case" statement to do per-machine settings.) Other than that -- I'd be happy to review (and use!) your changes. cheers luigi > it would be too presumptios of me to try and clean up, specialy since im > runing -stable, but since im planing on running many 'dataless' workstations > i've been fiddling around with several ideas. > > 1- i want more than one root-file server. > 2- i want the management of the ws to be as centralized as possible > 3- not all ws are the same. > > so, im willing to spend time/resources. > i've modified (slightly) libstand/bootp.c but haven't received any feedback, > (maybe because there isn't any documentation? :-) > > btw, whatever happend to the big rc change (ala sys5/linux)? > > danny > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-hackers" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
