I just found out that my TV's homebrew loader was partially bugged. Well, turns out i FOROT a simple & at the end of my launch script to send dinit into the background and hung the whole thing up XD Welp! Works now - no more update notifications. In fact, those update notifications is what tripped me; because part of the script is to edit the hosts file to block them and the update server.
Well, that problem is now gone. ^.^
I love how smooth this is though, once dinit kicks in, all my stuff just pops up and is right there; NAS usb drive... everything. So good. SyncThing too! ^^
Only weird thing: It is a 64bit CPU, but the whole OS is compiled in 32bit binaries O_o... makes no sense. That's a proprietary blackbox for ya.
