At some point these things reminded me the old sure way to defeat your
enemy (competitor) whom you can not defeat by force (by better product).
You just join him, then gradually lead him into the "black hole". I'm not
saying this _is_ what is happening, we will know that 5-10 years down the
road, but what I observe has all signs of this process. Luckily I migrated
my servers to UNIX several years ago (workstations still stay Linux
though).

We are doing exactly the same thing and for the same reasons.  We have

 Well, from what I've heard from some Red Hat RHEL Kernel guys, it will
 be
 likely in RHEL 8.x as default with a yum compat cli, but unlikely to
 get
 into RHEL 7.x as replacement for yum, and should stay confined to
 EPEL.
 The reason given was: "(DNF is) not quite Enterprise ready, yet. Lets

Sorry, I didn't mean it sound the way it sounded... Should have used
"rant" tags. I guess, it is just me in general unhappy about all Linuxes
getting much less "UNIX"y lately. Nothing about Linux, mostly about me not
blending into "iPad generation", I figure.

 There was a mail on the Fedora development list recently from one of
 the
 internal Red Hat RHEL yum guys.

 It implied that in RHEL the command would remain yum and not change to
 dnf,
 although the internals will no doubt do so at some point.

Well, striking an agreement so that RHEL can run on the Azure Cloud
(where SLES and Ubuntu and CentOS are already at) and on hyperv .. and
working with them to make Windows run better on KVM as a VM to me makes
perfect sense.  Other linux versions are already there (hyperv/azure)
and their customers want a paid RHEL option .. and people also need to
run Windows server for some things as a VM on RHEL KVM hosts.

I certainly don't want to start a flame war either way, but people with
customers need to do what their customers want .. and on both sides that
was for things to work together in their enterprise from both companies.

Of course, we can start a flame war and discuss how evil Microsoft is or
how evil money is or how evil global warming is or any other number of
things.  There will be many people on either side of all of those
positions .. but I'm not sure this is the forum for those discussions.

The bottom line for DNF, just like any other software that Red Hat
releases is .. if they build it and make it the default in RHEL, it will
become the default in CentOS .. we don't political or linux religious
wars (like systemd, selinux) here.  We build whatever source code Red
Hat releases when they release it.  Nothing more and nothing less.

 There was much wailing and gnashing of teeth when these changes
 rolled into Fedora.  After a while, I got used to it and now it seems
 normal. Plus, if you type "yum update" it responds "what your really
 should type is dnf update, but I'll do it for you anyway".

How about their recent agreements with Microsoft? That would be enogh
driving force for them to account for all changes we observed so far IMHO
(didn't look into dnf details so I exclude that for the moment from my

To make it clear here is the specific link on the fedora-devel archives
discussing this:

https://lists.fedoraproject.org/archives/list/de...@lists.fedoraproject.org/message/ALJVP7YTSEPC4HNH6JSFMFM6MCUP5HAT/

"Currently we're slated to keep yum as the primary name/command for package
management in RHEL. It may or may not be backed by dnf at some point; we're
still looking at the pros & cons and how to bring better compatibility if
we go down this path."

So my expectation is that RHEL8 will use dnf internally but the interface
will be called yum

Based on previous RHEL history I would agree with Yamaban's take
(probably in RHEL 8.x, likely not in RHEL 7).  But Red Hat has been a
bit less conservative with making changes to RHEL 7 than they were the
previous version of RHEL.

Still, for them to make a change there would need to be some driving
force for that change (IMHO).  For example, if there were new technology
areas (containers, cloud) where dnf had major functionality advantages
over yum, then they might consider a change.  Otherwise, I just don't
see it.

But, I have been wrong before .. a lot .. so take that with a grain of
salt :)

For users, it's a drop-in replacement.  If you write extensions, some 
migration is required, because the API has been cleaned up.


Is it supposed to work with CentOS or do we ignore it until some

[CentOS] dnf replacing yum?

2016-05-25 Thread Kenneth Porter
I saw mention of dnf in a blog article about installing a package on 
CentOS. Further investigation revealed that Fedora is replacing yum with 
dnf, apparently a new and better yum. But it wasn't clear if dnf was a 
drop-in replacement or if some migration setup was required. Is it supposed 
to work with CentOS or do we ignore it until some future release?




I installed dnf with yum and tried installing another package with it and 
it complains:


[root@orifice ~]# dnf install certbot
