Bug #6119 for PAR: Permissions of par-SYSTEM in temporary directory

Hello, My name is Brad Elliott and I am writing to report an issue with the Perl Archive Tool. The tool has been very useful in creating a perl application and distributing it as an application. Myself and a colleague recently stumbled across a rather unusual problem related to the permissions of the par-SYSTEM directory which seems to be created when running the perl executable. Basically there were two linux users trying to run a PAR generated application on the same machine. Whoever ran their application first had no problems because when extracting the application the par-SYSTEM directory was created as writable for this user. However, the permissions for this directory were read+execute for other all other users. Therefore, when another user tried to run an executable on the same machine after the par-SYSTEM directory already exists then they received a very generic error stating something like: directory or file does not exist: line 688 I don't remember the error off hand but I can provide more detail if necessary. We were running on version 0.8 of the PAR package on Redhat Linux with the TMP environment variable set to /tmp. If the user name was belliott, after extracting the executable a directory called /tmp/par-SYSTEM is created as well as /tmp/par-belliott. However, the /tmp/par-SYSTEM has permissions of 755 for user belliott and therefore no other user can write to the /tmp/par-SYSTEM. We worked around the issue by simply changing the permissions on the /tmp/par-SYSTEM directory to writable for the group but it may be possible to fix it in another manner or at least make other users aware if they see the same problem.
