From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Fedora Wants to Drop UEFI Boot Support on MBR (fedoraproject.org)

For those panicking about it, this is not something you need to worry about. Here’s what this actually does:

Enforce the use of GPT partition tables for all UEFI-based Fedora installations for x86 architecture. This removes support for installing Fedora in UEFI mode on MBR-partitioned disks on x86 systems

You probably have already been using GPT on your UEFI system since you had a UEFI system. Even if you somehow were using MBR, this probably;

  1. Won’t break existing installations, as it’s merely support for installs of this type
  2. Would not be a problem even if somehow the broke existing installs, as it’s not difficult to convert MBR to GPT.

Was it even a thing? I remember I had to choose MBR for legacy BOOT, GPT for UEFI.

I was wondering too why anyone would ever want this...but the proposal explains it:

Support for UEFI on MBR was originally added in blivet#764 to accommodate cloud image use cases, such as AWS, which at the time did not support UEFI booting on GPT disks. These constraints no longer apply to modern cloud platforms, making MBR-based UEFI setups unnecessary for current Fedora deployments.

So basically it was some workaround a few years ago. I have a hard time to see any reason speaking against the removal.

love all the folks getting annoyed by this who clearly didn't read the actual proposal

Since when is UEFI old? Wtf

[–] data1701d@startrek.website 14 points 1 day ago

That’s not what this is saying.

It’s only support for UEFI on the old MBR partition table - GPT partitioning has been the default for ages now.

Users move on from Windows because of old hardware compatibility, pick an easy to use distro, like Fedora. Fedora drops old hardware compatibility...

It's their second attempt in under a month. Red Hat needs to sit the fuck down.

[–] data1701d@startrek.website 26 points 1 day ago

As much as I resonate with the issues, in this case, this isn’t what they’re doing at all.

This drops support only for UEFI on the MBR partition scheme typically used by a BIOS setup, which I honestly didn’t even know was possible.

This ends support for no hardware - almost all distro installations on UEFI have defaulted to GPT partition tables for a long time.

I'd say look in a mirror and sit down, as you entirely don't understand this proposal. This is not something that impacts old hardware.

Rhel and Fedora are separate entities and work on their own, but they do influence each other.
