These are "nice to know" points. If you remember anything else, pls let me know. Tks I have started to working on it (for fun) in my spare time and I am having some success. I have set up the user/group in Cygwin to look more like Linux which is mostly working. I added the os definitions which were missing from portage. I am now at the stage where the file locks are not getting removed. The ":" might be tricky, however, I could use a managed mount for portage. Perhaps the offending packages could simply be renamed. I am only interested in getting Cygwin working so SFU not in my scope. I have not found Cygwin buggy, and even if it were broken, its just code that can be fixed... Do you have examples...
