I'm a neophyte regarding this ACL handling stuff.  Here is my usage model, which probably isn't that far from the model for many Cygwin users:  I use Cygwin to process/manage files within the c:\cygwin folder structure, and a very limited number of other folders/files (e.g. /cygdrive/f/backups/...).  I don't require complex security on any of these, and would like to keep things very simple.

1) Are there any ACL records that might be inherited from windows down into my structures (I'm in a corporate environment where the corporation "messes" with many things, so our windows might not be "as out of the box").
2) How can I detect/eliminate any ACLs within my folder structures of interest?
