What are dnf’s minimum memory requirements? It came as a surprise to me that a simple `dnf check-update` is getting OOM’ed by the kernel on a (ok, fairly small) 512MB VM.
[root@node ~]# dnf check-update
Killed
[root@node ~]# free -h
total used free shared buff/cache available
Mem: 480Mi 137Mi 292Mi 0.0Ki 50Mi 329Mi

[root@node ~]# cat /etc/os-release |grep -i pretty_name

[root@node ~]# dnf --version

According to [1], 1GB is required for a Fedora (desktop?) install but right underneath is a note that says only if I want to install it with lots of packages selected upfront.
With F28 Server (ships with dnf 2.7.5) this worked perfectly fine on an equally sized VM.
Anyway, is memory consumption a thing with the new libdnf-in-C++ efforts? Could a look into microdnf be a thing for me?
Any advice appreciated.
