RH would not be of much value if the support staff were not any more effective than the average end user.
Is this an ego thing?
It's only the boss that wants to pay for a safety net, forcing the issue of raising a ticket is their validation of money well spent I highly suspect. We're all human beings who are quite technical on this forum, you work for RH, the other guy works for someone else.
I have a suspicion that RH support is what the boss pays for as a backup should their employees be unable to solve a problem or decide to go to pastures new, as people do from time to time.
they're not, because they have no idea what they're looking for, they lack the subject knowledge and expertise, and they werent involved with directly producing a lot of the open source components they are having problems with.
By "engineer" I mean, "we are the people that wrote the actual open source components they are having a problem with". It would not be in their interests to hire us directly because 95% of the time the regular support people can do everything they need without things escalated to engineering.
My gripe about the original thread was bosses interrupting that investigation and telling the onsite staff to open a case elsewhere, IMO, that's disruptive behaviour.
I dont think this really happens, when we get these customer issues and the people who have tried to fix the problem are on the phone, they are lost / panicked / at a dead end. They are not like, "yeah we think it's ABC but our boss told us to call you". that's not really a thing. if customers can fix the problem, they do. they are not in a hurry to call redhat for things they can do themselves and they're not really supposed to since their support minutes are a finite resource.
What typically happens in this situation is the chap logging the ticket gets pissed off and says to the boss, "ticket logged it's with $vendor, I guess it doesn't need babysitting so I'm working on other tickets now".
The boss in this case is happy as it shows their earlier investment was a fine idea. The employee though is disgruntled as their toys were taken away and things it's not such a fine place to work.
For just ease of management and customization can't beat vanilla Debian
If you run the standard installer from a vanilla USB image, you will be asked questions about the config, most of which produce reasonable results if you just hit <enter>. Some of them will fail in certain environments. (No DHCP server? You will need to enter IP networking details.)
If you want to install a fleet of Debian machines (or VM images), you set up a PXE server and a set of answers to the installation questions, or you build an image for direct deployment, or you use the Debian VM image, or... whatever: there are a lot of possibilities that will work.
Most of this has been true for at least 3 Stables.
For these shops, you don't need the paid enterprise offering across the board (dev, testing, etc) so that is where an EL rebuild is handy. In those cases you don't want too much different between prod and test/dev, but you don't need the paid support or priority patches on internal test hosts.
