4 | # - if /dev is mounted (e.g. due to handover from initramfs or |
5 | # CONFIG_DEVTMPFS_MOUNT=y), remount with specific options | |
6 | # - some video drivers require exec access in /dev, thus it's set here | |
7 | # - for completness, we add few sanity limits (2k non-empty files, 16k inodes) | |
