[PATCH 2/2] fs: nfs: pick up network interface bootargs parameter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This adds the linux.bootarg device parameter from the network device of
the current nfs connection and adds it to the nfs bootargs line.

This allows booting from nfs without manually setting a ip=dhcp or
ip=<ipaddr> option.
