Linux Ethernet interfaces were named eth0, eth1, eth2, and so on.īut then we got the “everything at once” approach of systemd. What Happened To My Network Interfaces in RHEL 7, and Why? This week I’m starting a series of articles on other major changes and new features you will encounter not just in Red Hat but in all other recent distributions. How to configure the new journal daemon and how to extract journal entries was also looked at. We also covered how to transition from systemd from init and service control. A series of posts describing the Linux booting chain covered UEFI, UEFI – shim, GRUB Loader, the role of the kernel, and how systemd has replaced init. I have described many different aspects of systemd and the new Linux journal logging system, those are part of the RHEL 6–7 migration. These occurred between the release of RHEL 6 in November, 2010, and the release of RHEL 7 in June, 2014.

Several different communities working on different projects have independently made significant RHEL 7 changes. It’s not that Red Hat decided to change almost everything. There are enormous changes when upgrading from RHEL 6 to 7 (Red Hat Enterprise Linux).
