I checked the snapshot today and found the behavior to be matching what you described. An expected side effect right now is that old files still have the group SID set to the user SID as well as all the other installed files placed by the OS however there isn't much we can do there beyond changing the group manually for the files. On that note I used the larger inst package (to get updates to mkpasswd and the like) and noticed that there is a /usr/lib and /usr/bin folder with the updated files however cygwin mounts /lib and /bin on top of the respective folders making any files installed there inaccessible in a normal cygwin run. Is this intended? For now I manually moved those folders to the root therefore overwriting old files with the newer ones. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
