Logging as different user

[gtrashing]

Hi, I'm tring to write a script that as to be executed by root on linux...
This script execute other bash script normally like root, the problem was that I have to log what my script do. I choose the logging library...
Perhaps I have to write the log in a directory owned by a different user than root, in this directory root can't write and I don't know how write all log like this different user.

I've tried also to create another folder in the same (nfs) path with root owner but I got the same error:

Joss2:/opt/nfs/log # ls -l | grep reboot
drwxrwxr-x 2 jboss root     4096 Jun  5 12:59 reboot

Joss2:/opt/nfs/log/reboot # ../../bin/joss-reboot.py michael
