Can I rename my C:\Cygwin64 directory to C:\Cygwin?

Can I rename my C:\Cygwin64 directory to C:\Cygwin?

[Jim Reisert AD1C]

Now that Cygwin x86 is nearing/has reached end-of-life, I would like
to rename my C:\Cygwin64 directory to C:\Cygwin.

Other than updating my Windows environment variable (CYGROOT), are
there any "gotchas" in doing this?  I already have a D:\Home directory
specified in /etc/nsswitch.conf so I'm not expecting the move to break
that.

Where does setup.exe get its information from?  Is there a .ini file
that I will need to edit?

My main concern is that the Cygwin Perl installer may get confused.  I
currently have this in my Cygwin environment.  It doesn't appear that
such a change will be a problem:

  PERL5LIB=/cygdrive/d/Home/perl5/lib/perl5:/cygdrive/d/Home/perl5/lib/perl5:/cygdrive/d/Home/perl5/lib/perl5

Is there anything else I'm missing?

Please look for my earlier message[1](thread) regarding installation path
changes for provided PowerShell script.

Whoever it gets the information, you could easily change it the first time you
update the installation at the new place.
Consider it a non-issue.
The rest of the information is taken from `$InstallPath/etc/setup`

Depends on your setup, existing symlink targets may be a problem.
