Hi @Steve-Fister:

Are you copying the files over to /tmp? There should be quite a bit of space there as RAM disk, which is good for installing ipk packages. If there's still not enough space, you might consider extending the storage of your Omega with ext-root. You can find more information here: https://wiki.onion.io/Tutorials/Using-USB-Storage-as-Rootfs. Yes. It's quite unlikely to brick Omega by installing packages. Unless the package crashes the system on startup, in which case it will get into a boot-loop.

Hope you find this helpful.
Cheers!
