# - if /dev is not mounted - mount as a devtmpfs (CONFIG_DEVTMPFS=y)
# - if /dev is mounted (e.g. due to handover from initramfs or
#   CONFIG_DEVTMPFS_MOUNT=y), remount with specific options
# - some video drivers require exec access in /dev, thus it's set here
# - for completness, we add few sanity limits (2k non-empty files, 16k inodes)
