entware-setup.sh missing?

Running 3.0.0.4.374.35_2 and it seems "entware-setup.sh" isn't included anymore?

Also, tried following the "old way" described here:
https://github.com/RMerl/asuswrt-merlin/wiki/Entware
But, after doing:
"mkdir /mnt/sda1/asusware
touch /mnt/sda1/asusware/.asusrouter
reboot"

"cd /opt" returns error: "-sh: cd: can't cd to /opt"

EDIT:
Seems entware only supports MIPS, not ARM...
