4 Supported File Systems

You will need to adjust the IP address and the netmask to match your network configuration. The
500 in the example above should reflect your user id on the host system.
Don't forget to execute “
sudo exportfs –av
” after modifying
/etc/exports
. If you do this the
first time, make sure that you can mount the exported file system on your host or a different
machine on the same network before trying to boot your MatchPort from it.
Mounting NFS File Systems During Runtime
Client Side Prerequisites
In addition to the basic kernel support for NFS please ensure that the following two options are
enabled in your build:
CONFIG_USER_BUSYBOX_FEATURE_MOUNT_NFS
CONFIG_USER_PORTMAP_PORTMAP
The kernel configuration options
CONFIG_IP_PNP_DHCP and CONFIG_IP_PNP_BOOTP
are not
needed for this configuration.
portmap needs to run to support user space NFS mounting. Make sure that it is running or start it
like this from the command line:
/ # portmap &
Consider including the portmap call in a startup script if needed regularly.
AUFS
AUFS is an implementation of the idea to support mounts of several file systems into one single
mount point, one overlaying each other. This might be used to cleanly separate read-only data
from variable data.
We included a snapshot of AUFS into the kernel for your convenience. To see how this can be
utilized, refer to Chapter 5
