grml kernel, pxeboot and nfsroot

Hi,

I'm wondering if the default grml kernel is capable for pxeboot and 
nfsroot. 

There is only one thread in grml mlist mentioning pxeboot
http://thread.gmane.org/gmane.linux.distributions.grml.user/820

but I'm not sure what the conclusion is. Specifically, is the grml kernel 
built with the following features enabled as modules?

# DHCP support

CONFIG_IP_PNP=y
CONFIG_IP_PNP_DHCP=y

# NFS client support

CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
CONFIG_NFS_V4=y
CONFIG_NFS_DIRECTIO=y

# NFS root support

CONFIG_ROOT_NFS=y

Also CONFIG_AUFS_EXPORT should be enabled too, for me to export aufs as 
nfsroot from the server.
