Unplug a BPI-R3 router


Is it safe to unplug a BPI-R3 router with OpenWRT or could it cause filesystem problems?

Thanks in advance

OpenWRT is purpose-built for devices without power buttons and clean shutdown methods, so the root filesystem resides within a (usually sqashfs) image on the block device. This means that you cannot alter the files without re-flashing the entire root image. All the additional packages added are put into a separate space which is an overlay joining the root image with the user storage.

At worst case scenario, since the root image is always read-only (unless completely re-written in flash), only the user storage would become corrupted, meaning the openwrt would just be reset back to OOBE.
