Mistory of do_nfsmount

do_nfsmount is defined at two places, why?

  1. /scripts/casper +198

do_nfsmount function is getting called from /scripts/casper +188 which is from inside of


and depend on variable


The do_netmount() is getting called from mountroot() which is inside /scripts/casper +581 and the call depends on variable presense of variable ${NETBOOT} which is the boot parameter value of parameter netboot
