Learning RHEL now :)

Now would be the time to get out before IBM crushes RedHat's soul. IBM will squeeze RH for everything and more to get that cash pile back asap.

You're much better off learning core Linux utilities like from installing Arch, rather than outdated distro specific management.

  Assuming he’s coming from a Windows background learning core Linux utilities on Redhat is also possible. At least going through rhel he can reference the Redhat documentation which tend to be far better written than the million free guides out there. As a real life example, the other day I needed to migrate /var on a Linux box. The freely available CentOs guides covered it well, but when I was done the applications were having a lot of issues. Going through Redhat’s documentation it quickly became obvious that the other articles neglected to mention rebuilding the grub boot files and getting SELinux running on the new directory.

    Considering that after RHEL took over CentOS, they are again significantly behind RHEL, and RHEL isn't cost-effective... he could find equal support and probably much more from the Ubuntu community. CentOS or RHEL doesn't even have a public package search, and for good reason. When you find out that they are using an outdated kernel, and outdated qemu/libvirt components, you'll quickly find yourself installing RPMs from a bunch of different locations from Google searches.

      Looking at the "Delay" column in the release tables in Wikipedia, it appears that it's CentOS7 releases that have longer delays, the CentOS6 delays haven't changed in recent years (and there's nothing like the huge delays in 2011). Possibly because there are more packages being updated in 7? https://en.wikipedia.org/wiki/CentOS https://en.wikipedia.org/wiki/CentOS Package search is on https://git.centos.org/ https://git.centos.org/ For example, libvirt is at version 4.5 in CentOS 7.6, while CentOS 7.0 shipped with version 1.1: https://git.centos.org/rpms/libvirt/commits/c7 https://git.centos.org/rpms/libvirt/commits/c7 Whereas in Ubuntu 18.04 LTS, it's at version 4.0: https://packages.ubuntu.com/search?keywords=libvirt&searchon=names&suite=bionic&section=all https://packages.ubuntu.com/search?keywords=libvirt&searchon... The RHEL kernel's version number is doesn't signify as much as you'd think, there are whole subsystems backported into it from later upstream kernel releases.
