DSET 3.2: OS detection, SFCB service mandatory

I had two issues with DSET as well.
1. The same /etc/issue problem. We like many people probably modify /etc/issue in our SOE so using it to detect OS version isn't really a good idea. Dell should use lsb_release and OS specific files like /etc/redhat-release instead.
2. The much worse issue I came across when running DSET in the run once (not install) mode was that it modified system libraries and left them in a broken state.
It changes the /usr/lib64/libssl.so.10 symlink from pointing to libssl.so.1.0.0 to libssl.so.6. This causes any program linked to libssl 1.0 to now segfault.
A run once program like this should either request you have certain library versions installed, or it should be statically linked. It shouldn't modify system libraries and certainly not leave those modifications in place after it's finished running.
This is unbelievable behaviour for a diagnostics program which we should be able to safely run on production systems.

Subject: DSET 3.2: OS detection, SFCB service mandatory
PE-T620, CENTOS 6.x 2.6.32-220.23.1.el6.x86_64
I'm running DSET 2.2 and I realized DSET 3.2 is available on Dell web site.
I had 2 issues with DSET 3.2 install:
1) OS DETECTION
When trying to instal DSET there's a new OS detection
OS_NAME1=`cat /etc/issue | grep ESX`
OS_NAME2=`cat /etc/issue | grep SUSE`
OS_NAME3=`cat /etc/issue | grep Red`
Since we use CentOS, I had already rewritten /etc/redhat-release to match
what OMSA and other Dell software expect to find in it.
But now DSET looks at /etc/issue instead of /etc/redhat-release,
unfortunately we customize /etc/issue and it doesn't contain "Red Hat" or
Is looking at /etc/issue the new way all Dell software will use for OS
detection going forward?
2) New service mandatory:
Upon install this is printed on the screen:
The Small Footprint CIM Broker (SFCB) is a network service that enables
remote collection of system configuration information.
To perform the option that you selected, it is necessary to install and
start this service and leave it running in background for future
Continue installing/activating the SFCB on this system to listen for
incoming collection requests from clients.
Old versions of DSET would allow you to just run the diagnostics to send the
zip file to Dell support w/o installing anything permanent; the new version
not only didn't allow me to do that, but it wants to install a permanent
service (I already have OMSA 7 installed with its services running).
Is this new DSET service really necessary?
