How to pick a slice name

In general, slice names should be:

• at most 19 characters
• contain only the following characters: a-z,A-Z,0-9,- (uppercase and lowercase alphanumeric characters and dash)
• not start with '-' (i.e. dash)

Note: The '_' (underscore) character can not be used.

While enforcement of these rules is not consistent across all parts of GENI, following these rules will ensure compatibility throughout GENI.
