I don't think it is a bug either, but it is something I never really thought 
about.  If you do a make install running as root, then Bacula can execute a 
script which can call bconsole, and it can be very useful for certain 
operations.

I am not 100% sure about the security implications, which is one of the 
reasons I asked you to "take a look at it" rather than "please fix it". My 
basic instinct is to not change anything, because I am nervous about having a 
non-restricted console executable by anyone other than root unless the 
SysAdmin explicitly permits it.  That way, we ship something that we know 
doesn't have an unexpected security problem.

I've copied the bacula-users list as Jason suggested, so that if there are any 
good arguments for changing the current behavior, we can take them into 
account.

Best regards,

Kern

=========== Excerpt of bug #1134 ==========

Summary  	 
0001134: wrong rights on /usr/sbin/bconsole: can't use it in RunBeforeJob / 
RunAfterJob

Description 	
% ls -l /usr/sbin/bconsole
-rwxr-xr-- 1 root root 245328 Jul 23 13:58 /usr/sbin/bconsole

So bacula user can't run this binary, for instance via script shell(s) in
RunBeforeJob or RunAfterJob.

This binary should have bacula as group and be executable by this group.

Steps To Reproduce 	
- download and install bacula-2.4.1-1.src.rpm

- build binary RPM:
% % rpmbuild -bb --define "build_centos5 1" \
             --define "build_mysql5 1" \
             --define "build_python 1" \
             bacula.spec
