What part of FS into GL-MT6000 (Flint2) can be used as user permanent area and don't clean e.g. after official firmware update?
I have some files into root home, into self created /opt folder, some needed scripts into init.d etc.
But after update from official 4.6 to official 4.7 - lost this files. Router config was saved, so only webconfig was saved but not user files. Need part of FS that is not try to clean if firmware updated. Or instructions how to avoid file cleaning.
You can write the folders and files, that should not be touched during upgrade, into /etc/sysupgrade.conf
But: Uboot firmware flash will remove them for sure.
