CentOS

I split this away from its parent topic and moved it to the CentOS 7 section. The original was posted as a reply to https://forums.centos.org/viewtopic.php?f=54&t=73935 Your root filesystem is whatever gets mounted on / when you boot normally.

Boot a rescue media - like the install DVD in rescue mode - and mount your filesystems and rename it back.

Beside this, I had to update the CentOS systems from 7 to 8.

There is no supported "upgrade" from 7 to 8. It is a re-install. And in any case CentOS Linux 8 is already EOL, 2 years ago.

I've asked the main CentOS 7 dev about this but have yet to receive an answer. However, this package is not part of the main CentOS repos and things from the centos-sclo-rh used to be built by the CentOS SCL SIG and I am not sure that exists any more. We'll find out in a day or 6 what the answer may...

It would seem that you haven't been paying attention - Red Hat announced at the end of 2020 that they were canning the CentOS project as-was and replacing it with "CentOS Stream" which is a permanent beta product in which RH test fixes that will be in the _next_ version of RHEL.

I run AMD graphics on both my systems here, both F38 with kernel 6.7.5 and 6.7.6. I did have problems recently with crashes in amdgpu but that turned out to be due to my ATEN KVM having been reset to factory defaults and turning on a setting for MST. Once reset to SST the crashes have gone away but ...

I run Fedora 38 (now 39) on my Dell XPS13 Plus 9320 and that has an i5-1340P. I have not noticed any problems with it. And Fedora is rockl solid, not sure when you last tried it but I've been running it now since F32 and in that time I've had maybe 2 problems that were caused by Fedora and one of th...

Not sure how much simpler it gets. You're left at an emergency shell there. From that `mount -o remount,rw /` then edit /etc/fstab and fix whatever is wrong in it, save it, reboot.
