From c509c781ebc6ec536ddd5882e5cb9f119f49257c Mon Sep 17 00:00:00 2001 From: Mike Looijmans Date: Tue, 20 Oct 2015 08:43:47 +0200 Subject: initscripts/sysfs.sh: Mount devtmpfs on /dev/ if needed When booting from an initrd disk, or when the kernel config option DEVTMPFS_MOUNT isn't provided, /dev/ will not be mounted at boot. This small addition will check if /dev/ is "useful", and if not, will mount devtmpfs if the kernel provides it. With this change, it is possible to set an initscripts style image type to "cpio.gz" and boot it as initrd. Without this change, the image won't work properly because of the missing devices.
