[pve-devel] [PATCH proxmox 0/2] fix rootfs extraction when paths already exist

[Filip Schauer]

Remove paths from previous layers that conflict with new layer entries
before unpacking. This aligns with the OCI spec. [0]

This fixes a rootfs extraction failure with docker.io/grafana/otel-lgtm,
which was reported in the Proxmox Forum [1].
