That approach is essentially guaranteed to fail you in frustrating ways, for two reasons:
1) (Minor) You do not want to have setup itself, much less its work and data directory, inside the cygwin installation. I.e. that should never be '/' as the path for setup, as seen from any Cygwin shell.
2) (Major) Updating a running cygwin installation from the inside is highly unlikely to work correctly. Most importantly there is almost no chance for it to update the core DLLs, because those will already be in use by the shell you're running this from, so they cannot be changed. I.e. if you're in a situation where using "cygstart" makes any sense, that's a situation setup cannot update the DLLs.
In a nutshell, and to paraphrase a certain Mr. Ford, you can have your special non-interactive Cygwin setup script in any language you like, as long as it's effectively a _Windows_ batch file. Updating the branch you're currently sitting on does not work any better than sawing it through.
