I am using rawhide, and was trying to use dnf sometime ago, and
it was looking promising. But suddenly it stopped being useful,
and yum became again functional, so, I have been using only
yum.
And have been using yum with mock, because it does not work
with dnf, but now, when doing a review, I was surprised with this
in root.log:
DEBUG util.py:452: Executing command: ['/usr/bin/yum',
'--installroot', '/var/lib/mock/fedora-rawhide-x86_64/root/',
'--releasever', '23', 'resolvedep', 'ccache'] with env

'CCACHE_DIR': '/tmp/ccache', 'SHELL': '/bin/bash', 'PATH':

'HOSTNAME': 'mock'} and shell False
DEBUG util.py:388: Yum command has been deprecated, use dnf instead.
DEBUG util.py:388: See 'man dnf' and 'man yum2dnf' for more information.
DEBUG util.py:388: To transfer transaction metadata from yum to DNF,

ccache'
DEBUG util.py:388: No such command: resolvedep. Please use /usr/bin/dnf --help
DEBUG util.py:388: It could be a DNF plugin command.
so, lets run again (without fedora-review -o--yum) to ge back the dnf error
in root.log:
DEBUG util.py:452: Executing command: ['/usr/bin/dnf', 'builddep',
'--installroot', '/var/lib/mock/fedora-rawhide-x86_64/root/',

False
DEBUG util.py:388: No such command: builddep. Please use /usr/bin/dnf --help
DEBUG util.py:388: It could be a DNF plugin command.
I will review using a release other than rawhide.

I understand that there is need to update, to use new tools, but
I am afraid, yum only had a small window of time broken for me
some time ago, after that, I could simply not use dnf to update
rawhide, while with yum, sometimes needing --skip-broken (and
doing that when I knew the packages broken would not break
my system), I would be able to update.
