Ah, I see that Luakit runit misses some paths exports too!
UPDATE:
I've added these lines to luakit runit:
Code:
export PATH=/mnt/us/extensions/luakit/usr/bin:$PATH
export HOME=/mnt/us/extensions/luakit
export LD_LIBRARY_PATH=/mnt/us/extensions/luakit/usr/lib
And now luakit starts! The problem is that I can't fix all this kind of script issue in an automated way I guess... I only wonder why in KUAL the script doesn't need these lines to run!
