Recomended android 13 mount / rw how to?

Using /e/OS Build /e/OS
1

Hi Folks,
A bit of searching suggests attempting common remount of /system seems not supported in android 13.
/system and / seem on same partition, and:

1|redfin:/ # mount -o rw,remount /                                                                                                 
mount: '/dev/block/dm-8'->'/': I/O error
1|redfin:/ #

What’s the recommended procedure to write to /system (and / for that matter).
Thanks

Have you tried using TWRP ?

Thanks @piero, sorry for the (vvv) slow response… My enthusiasm to smooth out the wrinkles diminishes as I get use to the wrinkles…

So, why not TWRP - I guess mainly, why should I use TWRP? The phone (OS - /e/os) comes with rooted debugging available in Developer options, so if I have root by adb then I should be able to use it to do rooty type things, shouldn’t I? And, I figure there must be a way because that’s what root is for…

So, what I’d like to know - and should have asked - is how to use root via adb to mount / -w on Android/Linux 13?
