Confused about default mounted filesystems

Ask Fedora
1

Hi,

I’m fairly new to fedora coreos and currently experimenting with automatic deployment of VM’s in my proxmox environment. I’m confused by the default mount systems created, which differ from the scheme presented here: Mounted Filesystems

I did not provide any diks attributes in the ignition file and therefore assumed I would get the default mountpoints.

My output looks like this:

admin@amazing-vm:~$ findmnt --real

fc version:

I’m especially confused about the missing /usr mountpoint besides that the machine looks to operate normally. Nevertheless I would like to get a better understanding on what happened under the hood.

Regards, J
