Customizable Post-Install Script

Post-Install · Customizable~15 minView script

Cherry-pick exactly which optimizations to apply to a Proxmox VE host. ProxMenux groups ~30 individual tools into 10 categories, each with its own checklist dialog. Same engine as Automated, but with full control over what gets applied.

When to pick Customizable

Choose this path when you already know which tweaks you want on the host — or which you definitely do not want. The script presents a checklist per category so you can pre-select, deselect or mix-and-match optimizations. Every item can be applied again later (it is idempotent) or reverted from Uninstall Optimizations.

How it compares to Automated

Customizable is a superset of the Automated script. It covers the same 13 baseline optimizations plus a long list of opt-in ones that Automated intentionally skips — things that are useful only on specific hardware (AMD fixes), specific hosting (OVH RTM), or specific workloads (IOMMU/VFIO, Ceph repo, High Availability, Fastfetch, Figurine, ZFS ARC tuning, pigz, ZFS auto-snapshot, vzdump speed limits, Open vSwitch, TCP BBR…).

The 10 categories

The Customizable script groups optimizations into 10 categories. Each category has its own checklist dialog and its own documentation page — open one of the cards below for the per-option rationale, defaults and verification steps.

Basic Settings
Clean the APT sources, run the official Proxmox upgrade and set timezone, locale and common utilities. The baseline every other group sits on top of.
System
Tune the log subsystem and kernel limits for a host that carries many VMs and containers. Covers journald, logrotate, sysctl (memory, file limits), kernel panic behaviour and fast reboots.
Virtualization
Prepare the host for advanced virtualization. Auto-installs the guest agent on templates and enables IOMMU/VFIO for PCI passthrough of GPUs, controllers and TPUs.
Network
Harden and tune the host's network stack. Forces APT over IPv4, applies sysctl hardening + TCP buffer tuning, offers Open vSwitch and BBR, and pins persistent interface names by MAC.
Storage
Set up Proxmox's common storage subsystems: ZFS ARC sizing, ZFS auto-snapshot, and vzdump speed limits to avoid saturating the disk during backups.
Security
Reduce the attack surface exposed by default. Disables the RPC services (portmapper/rpcbind) that Proxmox does not need but leaves listening.
Customization
Change the host's visual and shell experience: colors and aliases in bashrc, MOTD banner and removal of the subscription notice in the web UI.
Monitoring
Integrate the host with OVH Real-Time Monitoring. Only appears when ProxMenux detects an OVH server.
Performance
Speed up compression operations (backups, transfers) by replacing gzip with its parallel counterpart pigz.
Optional
Niche pieces not every host needs: AMD CPU fixes, Fastfetch banner, Figurine 3D hostname, Ceph repository, High Availability services and Log2RAM to reduce SSD wear.

Mix Automated and Customizable

A common pattern: run Automated first to lock in the sensible baseline, then open Customizable and pick only the opt-in tools you care about (for example, IOMMU on a host that will do GPU passthrough). Changes are tracked independently; the Uninstall menu shows everything you have applied regardless of which path added it.
