This is intentional - if you leave the system in readwrite, the SD card is likely to die after a few months or even weeks of operation. That's why I switched to readonly rootfs, and moved all data that needs to be writable into the /flash partition.
You can switch the root partition to rw by editing /etc/fstab (change ro to rw in the line "/dev/mmcblk0p2 / ext4 ro,noatime,nodiratime 0 1"), but I do not recommend doing so except for experiments. For everything that should run 24/7 you should use readonly rootfs.
Best Regards,
