wrong UNIX filesystem root

[nikolaydubina]

docker image build expects models to be stored in '/root/.llama/checkpoints/`

however, elsewhere in code and documentation it is expected to be in /.llama/checkpoints/‹model name>

having /root/... is very odd. on UNIX file systems root should be just /

I was having this issue bellow. moving files into /root fixed it, meaning it is indeed looking not into / but into /root.

os.getenv("LLAMA_STACK_CONFIG_DIR", os.path.expanduser("~/.llama/"))

The default path is in os.path.expanduser("~/.llama/"). You may set LLAMA_STACK_CONFIG_DIR to change the path of model checkpoints.
