poky-nfsroot

Example steps to use:

Prepare your local.conf:

echo 'INHERIT += "nfsroot"' >> $BUILDDIR/conf/local.conf
echo 'IMAGE_FSTYPES:append = " tar.gz"' >> $BUILDDIR/conf/local.conf

Build your rootfs recipe:

bitbake my-rootfs-image

Start the update server:

nfs-export-updater --debug my-rootfs-image <exportdir>

This will

• extract the rootfs tar archive to the folder <exportdir> if this does not exist yet. If the argument is omitted, the default folder name nfsroot-<image>-${MACHINE} will be used instead.
• start a unfsd instance on this folder

To update the nfsroot, it's sufficient to just build the recipe in question. To copy files into the nfsroot, use nfs-cp, e.g. nfs-cp ~/nfsroot/myboard fstab /etc/fstab.
