Subject: NFS: Add support for debian based distros
X-Git-Tag: 0.1~58
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3da03a60365a15419660f1aeb7c307c7c5192bd6;p=platform%2Fupstream%2Fdracut.git

NFS: Add support for debian based distros

This patch enhances nfsroot and the nfs test-suite with compatibility
for debian based distros. This is mainly the difference of using
portmap instead of rpcbind and the missing file /etc/netconfig
