[pve-devel] [PATCH installer v3 09/20] debian: strip unused library dependencies

[Christoph Heiss]

Rust links in some dynamic libraries even if only used by a disabled
feature gate.

This will be needed due to moving http-related code into the
proxmox-installer-common crate and thus pulling it in at more places.
