Booting 18.04 with overlay fillesystem
I have an arm based embedded target with emmc and sd card.
The 18.04 rootfs is on
/dev/mmcblk0p2. Kernel version is 4.14 and overlay filesystem is enabled. Kernel and device tree are on/dev/mmcblk0p1Before making it read only, installed overlayfs package with apt-get and set
overlayroot=tmpfsin/etc/overlayroot.conffile.using uboot to load kernel and bootargs are:
earlyprintk loglevel=8 uio_pdrv_genirq.of_id=generic-uio root=/dev/mmcblk0p2 ro rootwait rootfstype=ext4
After above setup: I still see rootfs is mounted on /dev/mmcblk0p2.
Am I missing anything?
