Those of you unfortunate enough to have encountered the Dell technical suport department will know their love for the Dell diagnostic tools. Those of you who run CentOS and have been asked for a DSET report (Dell System E-Support Tool) will also know that the DSET tool refuses to run on an “unsupported” operating system.
Luckily, DSET is quite easy to trick – just add the following to the top of /etc/issue (assuming that you’re running CentOS 6):
Red Hat Enterprise Linux Server release 6 x86_64
Now DSET will work as normal, blissfully unaware that it is running on CentOS and not RHEL. Remember to take the line back out again once you’ve finished with DSET.
