+Another form of netboot by downloading a squashfs image from a given url.
+The fetch method copies the image to ram and the httpfs method uses fuse and
+httpfs2 to mount the image in place. Copying to ram requires more memory and
+might take a long time for large images. However, it is more likely to work
+correctly because it does not require networking afterwards and the system
+operates faster once booted because it does not require to contact the server
+anymore.
