@domubpkm I think judging by the fact that even after remounting / as rw i cant install packages due to space problems, it is that, but i dont know how to increase the size of my / partition because all guides assume that the system image is simply placed in /userdata/system.img, which it isn't for the FP5 as it has dedicated partitions. If someone can help, please do so.

I installed fresh for first install and i am having issues with some apps not working, like uAdBlockNG and Libertine containers seem to be bugged, requiring adding „extrausers“ to the first 4 lines of /etc/nsswitch.conf for the phablet user to work properly.
