*sys-package-mgr*: can't create package cache dir

We hit another issue today after applying a fix pack to our WAS system, like the osgi bundle issue, it was due to file permissions.

When we were running some jython scripts, we were trying to import some packages but got an error:

from org.python.modules import re
WASX7015E: Exception running command: "from org.python.modules import re"; exception information:
com.ibm.bsf.BSFException: exception from Jython:
Traceback (innermost last):
File "", line 1, in ?
ImportError: no module named org

To recreate the error, rather than running this in a script I just started up a wsadmin session and on doing so I got the following error:

*sys-package-mgr*: can't create package cache dir, '/temp/cachedir/packages'

After a bit of investigation, it turned out the "cachedir" directory was owned as root but we run our scripts as a WASAdmin user. It looks like the permissions were changed to root after applying some fixpacks a couple of weeks ago, so a simple chown on cachedir resolved the issue.
