# Include dracut's NFS module in the live installer initrd.
#
# Without it, `root=live:nfs://<server>:/<path>/squashfs.img` fails: the kernel
# NFS modules ship in the initrd, but dmsquash-live/url-lib.sh only registers
# the NFS handler when `nfs_to_var` is present, and that helper comes from the
# dracut `nfs` module.
#
# kiwi builds the live initrd by running dracut inside this image root, so this
# drop-in is merged with kiwi's own 02-livecd.conf (dmsquash-live, livenet,
# pollcdrom). Both use `+=`, so the module lists accumulate.
