Ignore the handbook. Try 'man diskless'. kenv is only used in current's rc.diskless scripts, and it resides in /bin on -current. kenv is not used in 4.x's diskless scripts. Basically what you do is create a files and directories in /conf/base and /conf/default which are used to populate the MFS/MD root and other directories. I have included my setup at the end. :I was running a VIA Mini-ITX diskless box off a 4.7-STABLE box for a :while using a root fs created by the clone_root discussed in the :handbook, then some tweaks. I'm having a heck of a time trying to get :this running under 5.0-RELEASE, now sync'd to 5.0-CURRENT as of :yesterday, then mergemastered. : :If someone can provide some clues or pointers, I'd be happy to doc how :I get it to work (for the Handbook?) and could take a stab at updating :clone_root for 5.x if it's needed. : : :Background: : :Been using FreeBSD since 2.2.x. I can code. I can RTFM. :-) : :I've read the 5.0 Release Notes and Early Adopters docs. :... : :Upon boot, after kernel loaded, console shows a bunch of rc.conf-style :vars being set, then spews some debugging which I put in :$DISKLESSROOT/conf/default/etc/rc.d/diskless, so it's running that :rather than the old /etc/rc.diskless* files. I've moved the "mount -a" :near the top of rc.d/diskless since it runs commands which are and not :available until /usr is mounted (e.g., mtree). The NFS mount fails :with a message I don't understand: : :Can someone point me in the right direction ? Thanks! I'm not sure what you are doing here. You don't want to override any rc.d files in /conf. That will blow things up for sure.

You can also use /conf/base/.remove and /conf/default/.remove files to list files to remove from the clone. You don't have to specify a network config in your /conf/default/etc/rc.conf because the network will have already been setup. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
