First release ready for use
Notes:
-opkg will work after installing
-Everything opkg does is installed to /opt
-/opt is actually located at /usrdata/opt to save space but is mounted at /opt
-Anything opkg installs will not be available in the system path by default but you can get around this by symbolic linking each binary installed by the package to /bin and /sbin from /opt/bin and /opt/sbin
For example:
opkg install zerotier
ln -sf /opt/bin/zerotier-one /bin
ln -sf /opt/bin/zerotier-cli /bin
ln -sf /opt/bin/zerotier-idtool /bin
Now you can run those 3 binaries from the shell anytime since they are linked in a place already part of the system path.
Change installation from /opt to /usrdata/opt
There is more room to work with at /dev/ubi2_0 which is where /usrdata is mounted from.
From stock firmware ubi0 (rootfs [/]) only has 49.3 MBs free while ubi2_0 has 119.8 MBs
