> Snapshots of a snapshottable directory are allowed to have arbitrary names. Presently,
if you create a snapshot with a snapshot name that begins with a "/" character, this will
be allowed, but later attempts to access this snapshot will fail because of the way the {{Path}}
class deals with consecutive "/" characters. I suggest we disallow "/" from appearing in snapshot
names.
> An example of this is in the first comment on this JIRA.
