converting to RHEL8...
Welcome to my "convert to RHEL8" blog. As you might know, I have been running Red Hat, SL and CentOS machines for about 25 years now. Lacking SL-8, latest incarnation of this series is CentOS-8 and now powers-that-be instruct us to use RHEL-8 instead. So, Here we go. Conversion from CentOS-8 to RHEL-8 in 5 easy steps. Main announcement of "16 free RHEL subscriptions" per "developer": https://urldefense.proofpoint.com/v2/url?u=https-3A__www.redhat.com_en_blog_new-2Dyear-2Dnew-2Dred-2Dhat-2Denterprise-2Dlinux-2Dprograms-2Deasier-2Dways-2Daccess-2Drhel-3Fsource-3Dblogchannel-26channel-3Dblog_channel_red-2Dhat-2Denterprise-2Dlinux&d=DwIDAw&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=IBWdeVmMPbkgwCr8Ir6R307eFH3-2aZ9vYnQ7mEhhHM&s=Nr6cQ40qpd7tUZVaiCs5XQ0MyOB6xi3VeKjzLmSVuYQ&e= I do have a RedHat developer account. A few weeks ago, there was nothing there, as of a few days ago, there is a "1 active subscriptions" page, as of today, there is a "using 0 out of 16 entitlements" page. (I do not see any email notices about all this activity and I do not see any blog messages about this. So communications can be improved). I also see a link to download RHEL8 ISO and DVD images, I did not try it yet. So far so good. BTW, when logging into the RedHat developer account, there is a number of click-through agreements to "agree" with. Read them. If you do not like them, tough! Instructions for converting CentOS to RHEL are posted here: https://urldefense.proofpoint.com/v2/url?u=https-3A__access.redhat.com_articles_2360841&d=DwIDAw&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=IBWdeVmMPbkgwCr8Ir6R307eFH3-2aZ9vYnQ7mEhhHM&s=Hhj0voUDSXlQKw63jIuVJYcerY5Bmru62tOJwbHKuMk&e= They start with "hire Red Hat to do the job" (fair is fair, nothing better than expert help!), and move to the Convert2RHEL tool. This tool, at https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_oamg_convert2rhel_&d=DwIDAw&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=IBWdeVmMPbkgwCr8Ir6R307eFH3-2aZ9vYnQ7mEhhHM&s=abbG4Y8cEtfUdozsmDGSszrCG5MueYPy9xL-1FiW348&e= , does not appear to be an official Red Hat or CentOS product and I see only one author/maintainer listed, from Vsetín/Czech Republic. A tool directly developed and maintained by RedHat/CentOS would have been much preferred, especially by those worrying about "supply-chain" integrity. convert2rhel-0.15-1.el8.noarch.rpm from github is not signed, not even by the author, so the chain of trust going from "everything signed by centos" to "everything is signed by redhat" is not preserved. The possibility of downloading and running a trojaned conversion script is not eliminated. Next, I see this: "Known issues: UEFI-based systems cannot currently be converted to RHEL. (BZ#1899314)", I am not sure if my CentOS-8 test system uses UEFI or Legacy boot, but I am not worries about this, fixing "broken grub" boot problems is routine. As likely as not I will replace the grub2 boot loader with syslinux, which is much more stable and also easy to debug. Next, I do not see in the instructions the step for obtaining and installing a Red Hat subscription activation key. I assume I get the activation key somewhere in my Red Hat developer account, but I did not find the button to do this yet, and I do not know what to do with the activation key anyway.

Identically named RPM's do not necessarily have identical contents. To do a really *thorough* switch, you need to reinstall *everything*. I used to publish scripts for this, for switching from RHEL to CentOS to Scientific Linux and other combinations. Nico Kadel-Garcia

So you recommend as last step of conversion to run this:
foreach $rpm {
yum reinstall $rpm
}
I suspect this is unnecessary, but you are right, one will have a mongrel system
unless it is done. But do you know of any case where it makes a practical
difference?
Even way back when?

Time to dust them off, I guess.

Re: converting to RHEL8...
If in doubt, i always did a fresh install, so never had a messup. Conversion? Never ever. Dot. I am running SL7.9 of FermiLab now. Im sure RH will continue to share updates. There is no spilt milk, why cry? If needed, i will have a follower OS prepared in good time ready to switch to. (Checkouts with VirtualBox since a long time). Where to go later? Dont think it will be debian then; I read DistroWatch now and then Regards, Rainer ### -- On 2/4/21 7:07 PM, Konstantin Olchanski wrote: On Mon, Feb 01, 2021 at 12:26:00PM -0800, Konstantin Olchanski wrote: Here we go.
