state trees cannot have 'dots' in the name

[grep4linux]

It looks like wee need to either document that states cannot have dots in the name or add that functionality. I had a customer ask about this.

Example:
Given the following state tree:

bogus.dot.state/
└── init.sls

Salt sees it as:

salt minion01 cp.list_states
minion01:
    - bogus.dot.state

Running the state produces the following error:

# salt minion01 state.sls bogus.dot.state  test=True
minion01:
    Data failed to compile:
----------
    No matching sls found for 'bogus.dot.state' in env 'base'

If I rename the state to remove 'dots' then it works.

@grep4linux, thanks for the report.

We had one at one point but it looks like it got unlinked at some point.
