Red Hat Enterprise Linux (RHEL) Room for Improvement

System Analyst II at a energy/utilities company with 1,001-5,000 employees

I'd like to see more of NCurses type menu systems in some instances. We're dealing with SUSE Enterprise Linux, they have an NCurses menu system. It's a menu system. Even some of the higher-end Unix systems like AIX have some inner menu system where all the configuration tools are right there so your administrator doesn't have to jump through multiple directories to configure files if needed. I like the simplicity of Red Hat because it's pretty easy but having an NCurses menu when you have to get something done quickly would be nice.

Linux overall needs improvement. They cannot go much beyond what Linus Torvalds's kernel implementation can do. I come from AIX, and there were very cool things in AIX that I am missing dearly, e.g., being able to support not only adding, but also reducing memory and number of processors. That is not supported on Linux right now, and it is the same for the mainstream file systems supported by Red Hat. There is no way of reducing a file system or logical volume. Whereas, in AIX, it was a shoo-in. These are the little things where we can say, "Ah, we are missing AIX for that."

We are not loving our servers anymore. If we need them, we create them. When we don't need them, we delete them. That is what they are. They are just commodities. They are just a transient product.

Sometimes they don't have new versions for applications like Apache or PHP. I understand it's because they have to have support for them, so they can't have the latest version all the time, but that's the main thing I see that could be improved.

So when you use RHEL and you want to install, let's say, Apache or PHP, you do a "dnf install php" and you get a specific version that Red Hat releases. But that isn't the latest version that PHP has released, because Red Hat has to make sure that they can support it. The compatibility with the latest version of Apache or PHP lags because RHEL does not release updates of the latest versions.

It's the same with the kernel. Sometimes they are a bit behind in the kernel version. That's the same issue. They have to test it and support it for so many years so that's why they are a bit behind on the kernel as well.

Their pricing and documentation can be improved. They need to have developer variance that's more developer-friendly and less costly. They have a free developer version, but that's very limited in terms of features from RHEL. They also need to build their own open-source community.

It is mostly better than other solutions. However, it is sometimes difficult for disaster recovery, so we have to plan accordingly.

It could be a bit more user-friendly. It could also be cheaper.
