Hello,
I see that when you copy Cygwin executables (and dlls) to a random
windows machine and run (for example) bash.exe that Cygwin treats the
parent directory as the root, assigns it an 8-byte serial number and
records it in the user registry. Can somebody point me to where the
code is that does this? I presume somewhere under winsup/cygwin?
Also, are there pretty docs somewhere that detail the Cygwin internals,
architecture, etc? It's making me curious...
Thanks!!
Daniel

The internals are not overly well documented. There are a few how* txt
files in winsup/cygwin but they are old and partially outdated. I try
to write extensive git commit messages and inline comments whenever I
change stuff and also try to convince other contributors to do that,
too.

Thank you Corinna! And sorry for the delayed response.
Maybe this is something I can put on my TODO "wish list" -- going
through the Cygwin docs, learning the internals a bit better and maybe
adding to them. It's always nice to have a nice doc explaining the
high-level architecture and then other docs to "drill down" to the
details on certain areas. I've always been amazed by what Cygwin does.
