Hi , apoklyps3

Your linux is embedded ( for that Your "rootfs" ( "/") is in like RAM drive/disk ( as temp/pivot root ) -> then you cannot remount for r/w and this only r/w only at runtime ). )

( Your firmware in the flash ( mostly ) loaded to the RAM at the boot stages by bootloader ( like u-boot ).. )

Your "/dev/root" device is mounted to (/) point that is "read-only fs" with squashfs ( compressed ) that located in the flash ( or sometimes sdcard ? )
it should contains all binaries , startup files , default config files and the others....

* Your mount command is wrong as already @Corona688 said this.
* And you cannot re-mount the squahfs for r/w ( try with "/dev/root" lets see what happen or not )

Your device ( /dev/mtdblock5 is read/writable block device ( Flash or disk-on-chip ) with "rootfstype=jffs2" and
then you can read the some configs or other related files from it.
But also you can write via "/dev/mtd5" ( safe way ) char device to flash partiton which is writable side.
Shortly , mount command works via block device and must used via the char device for i/o operations..
Your ( /apps ) mount point is writable and has contains user apps/data/configs ( already i said above ) and these are permanent.
Look at the some details..
Managing flash storage with Linux

( the others are Kernel partitions from RAM or other memory chips ( ssd ? ) .. )

* You can look for the details of the flash partitions ( "cat /proc/mtd" )

Now i m not sure is there a easy way ? , ( because i have no knowlodge about the routers and firmware )
But i can say , you have to create the customized firmware and you must flash it to router for permanent solution.. ( if it has not nvram settings for non-squash filesystem support )
( or you must unsquashfs to extract the contents to writable partition then mksquashfs to create new image from thises and write it to the target mtd device ( like "writemtd.c" codes or image dump tools )

Another try , you maybe update the router firmware with ( open-source ) alternatives like dd-wrt , open-wrt .. ( if your product ( Kaon media ) vendor does not the new firmware..)

But best way as @Corona688 said , you must update the new firmware from original Kaon hardware vendor if there is..

Good lucks

NAME

       ifpgui - Open source GUI for iRiver's iFP flash player

SYNOPSIS

       ifpgui

DESCRIPTION

       ifpgui is an open-source graphical user interface (GUI) for iRiver's iFP flash players.	It uses libifp to access the player using the man-
       agement interface.  In addition to moving files onto or off of your iFP device, you can use this program to upgrade its	firmware  or  view
       the battery charge level.  You can also set station names in the radio tuner, and more...

       You  can  only  use  this software if your player has the "Management" version of iRiver's firmware installed.  iRiver also releases a mass
       storage (UMS) firmware, which allows you to access your iFP device as if it were a USB hard disk drive.

       libifp is known to work on the following players: iFP-1xx,3xx,5xx,7xx,8xx,9xx and N10

FILES

       ~/.ifpgui_rc
