I'm not mirroring or using kickstart. os only.

For previous versions, I was able to reduce the size of the updates mirror

How does the observation looks like, when all

Here's another interesting observation.

For previous versions, I was able to reduce the size of the updates mirror 
significantly by running repomange -o and deleting the resulting files on next 
sync. With the AppStream repo, this no longer works, the anaconda installer 
will complain that at least one package has an incorrect checksum, and the only 
way to remove this error is to restore the complete package set, multiple 
versions and all. I've not been able to narrow it down more.

[CentOS] CentOS 8 installation

[isdtor]

Are there still a lot of rough edges in this area? There are some things I 
simply can't get to work.

This is about kickstart installations. Finding the right stuff for the 
%packages sections is lucky dip at best. The RHEL manual points to the comps 
file, really? This file isn't meant to be parsed by humans.

Specifying an environment - the example "Infrastructure Server" doesn't exist. 
Is this one of the areas where CentOS deviates from RHEL? I did find 
server-product-environment, custom-environment, minimal-environment.

I followed the link in the documentation to the kickstart file generator. The 
generated file isn't usable as is, specifically the %packages section - 
anaconda says there is no group dns-server, for instance. Which dnf later 
confirms. The group list in dnf also seems to be a lot shorter than it used to 
be under 7?

Specifying %packages --multilib, this is where it breaks down completely. For 
the chosen group/package mix, which works perfectly without multilib, anaconda 
complains about conflicts for files provided by both the i686 and the x86_64 
version of, in this case, gdb-headless and sssd-common. Attempting to fix this 
with

-gdb-headless.i686
-sssd-common.i686

fails, these lines are being ignored. Excluding gdb-headless altogether fails 
also because the main gdb package pulls it in.

Honestly, I'm not sure where to go from here.

If you read my question, you would have answered "No. There is no utility
that I'm aware of."

Thank you for pointing me to the information, which I have already seen. I
was wondering if someone has coded up a script already to check a running
system, before I do it myself.

If you read the ElRepo Blog, you would know the following:

You can check by running the lspci command (lspci -nn) and compare it
with Red Hats list of removed ID's:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/considerations_in_adopting_rhel_8/hardware-enablement_considerations-in-adopting-rhel-8#removed-adapters_hardware-enablement

Here is the list of all (so far created) the DUD's for EL8:
https://elrepo.org/linux/dud/el8/x86_64/

And here is ElRepo page http://elrepo.org/tiki/DeviceIDs that shows all
the drivers ElRepo has the drivers for, and can create DUD ISO files if
asked via ElRepo bugzila:

Re: [CentOS] CentOS 8 Installation Not Recognizing Local Disk

[Ljubomir Ljubojevic]

Hi guys.

Somebody should use info from my mail
(https://lists.centos.org/pipermail/centos/2019-October/173682.html) to
create a page in Wiki and maybe even special notice on main Web page, it
looks like next few months people will continually ask for that info as
they go to move to install CentOS 8.

It might be worth thinking over how to provide that info (Wiki) inside
installer for 8.1, 8.2, etc. if no disks are detected.

Is there a utility somewhere to check a running system to see if it is
going to be supported in RHEL/CentOS 8?

Re: [CentOS] CentOS 8 Installation Not Recognizing Local Disk

[Nux!]

There was a recent thread about Redhat's removal of drivers from LSI 
SAS2, it's probably the problem you are facing.

It can be worked around with the help of Elrepo repo.

[CentOS] CentOS 8 Installation Not Recognizing Local Disk

[Brewer, Mitchell]

I have an older Dell PowerEdge server with one hard drive, with CentOS 7 
currently installed. I wanted to do a clean install of CentOS 8, but it doesn't 
pick up the hard drive. When I click on the destination to pick the hard drive 
it only shows the USB drive that I'm installing from. I checked for a RAID 
configuration on the server, but there is only one disk, and no RAID is 
configured. The disk is controlled by the PowerEdge Raid Controller (PERC), but 
when I disable that I lose the disk completely. I suspect that PERC is part of 
the problem, but a CentOS 7 install proceeds normally with PERC enabled. Do you 
know of a change from CentOS 7 to 8 that would cause this, or if there is a 
workaround? I've searched for several days and haven't found anything yet.
