[OE-core] wic wks: data partition only mounted on second boot?

[Matthijs Vader]

Hi,

I have my wks file like this:


part /boot --source bootimg-partition --ondisk mmcblk0 --fstype=vfat --label boot --active --align 4 --size 16
part / --source rootfs --ondisk mmcblk0 --fstype=ext4 --label root --align 4
part /data --ondisk mmcblk0 --size 100M --fstype=ext4 --label data --align 4


It creates the /data partition, and adds it to the .wic file, all fine. But on
the first boot it is not auto-mounted. From the boot log:


[    1.898069] EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
[    1.906798] VFS: Mounted root (ext4 filesystem) readonly on device 179:2.
[    1.919446] devtmpfs: mounted
[    1.923113] Freeing unused kernel memory: 264K (c069e000 - c06e0000)
version 2.88 booting
Starting udev
[    2.535288] udevd[657]: starting version 182


And some extra info:


root at beaglebone:~# mount
/dev/root on / type ext4 (rw,relatime,data=ordered)
devtmpfs on /dev type devtmpfs (rw,relatime,size=243816k,nr_inodes=60954,mode=755)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
debugfs on /sys/kernel/debug type debugfs (rw,relatime)
tmpfs on /run type tmpfs (rw,nosuid,nodev,mode=755)
tmpfs on /var/volatile type tmpfs (rw,relatime)
devpts on /dev/pts type devpts (rw,relatime,gid=5,mode=620)

root at beaglebone:~# cat /etc/fstab
# stock fstab - you probably want to override this with a machine specific one

/dev/root            /                    auto       defaults              1  1
proc                 /proc                proc       defaults              0  0
devpts               /dev/pts             devpts     mode=0620,gid=5       0  0
tmpfs                /run                 tmpfs      mode=0755,nodev,nosuid,strictatime 0  0
tmpfs                /var/volatile        tmpfs      defaults              0  0
/dev/mmcblk0p3  /data   ext4    defaults        0       0


Now, if I just reboot the device, the extra image is mounted during startup:


[    1.897948] EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
[    1.906674] VFS: Mounted root (ext4 filesystem) readonly on device 179:2.

[    3.193848] udevd[664]: starting version 182


And also mount shows it mounted:


root at beaglebone:~# mount
/dev/root on / type ext4 (rw,relatime,data=ordered)
devtmpfs on /dev type devtmpfs (rw,relatime,size=243816k,nr_inodes=60954,mode=755)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
debugfs on /sys/kernel/debug type debugfs (rw,relatime)
tmpfs on /run type tmpfs (rw,nosuid,nodev,mode=755)
tmpfs on /var/volatile type tmpfs (rw,relatime)
/dev/mmcblk0p3 on /data type ext4 (rw,relatime,data=ordered)
devpts on /dev/pts type devpts (rw,relatime,gid=5,mode=620)


Any ideas how to make it boot during the first boot as well?

Thanks, Matthijs
