Source ~/.config/update-notify/config to override THRESHOLD, AUR_REPO
and KERNELS, so settings survive package upgrades. The threshold
argument still takes precedence, so drop it from the service. Add a
commented sample config.

update-notify

Desktop notifications for pending updates on Arch Linux.

update-notify runs on a systemd user timer and checks:

Repo updates, using checkupdates from pacman-contrib.
AUR updates for packages in a local aurutils repository (aur repo -u).
Custom kernel rebuilds: when a stock kernel (e.g. linux-lts) has a newer version than your custom build of it (e.g. linux-lts-custom).

It sends one notification, and only when its content changes since the last one:

Update counts are shown once the total number of updates reaches a threshold (default 30). Reminders for git-monitor and pending firmware updates (fwupdmgr) are added when those tools are installed.
Kernel rebuild reminders are always shown, even below the threshold.

Requirements

pacman-contrib
libnotify and a running notification daemon

Optional:

aurutils: check AUR packages in the local repository
fwupd: check for firmware updates
git-monitor: remind to check git packages

Installation

Build and install the package with the included PKGBUILD:

makepkg -si

Or, with aurutils, build it into your local repository with aur build and install it with pacman.

Then enable the timer:

systemctl --user enable --now update-notify.timer

The timer runs 5 minutes after boot, then every 6 hours.

Usage

update-notify [threshold]

threshold is the minimum number of updates (repo + AUR) before update counts are shown. It overrides the THRESHOLD setting below.

Configuration

Settings are read from $XDG_CONFIG_HOME/update-notify/config (default ~/.config/update-notify/config), a bash file that is sourced by the script. All settings are optional:

THRESHOLD: minimum number of updates before update counts are shown (default 30).
AUR_REPO: name of the local aurutils repository (default aur-local).
KERNELS: maps each stock kernel package to its custom build (default: linux, linux-lts and linux-zen to <name>-custom). Kernels where either package isn't installed are skipped. Set KERNELS=() to disable the kernel check.

A commented sample config is installed with the package. To start from it:

mkdir -p ~/.config/update-notify
cp /usr/share/doc/update-notify/config.example ~/.config/update-notify/config

Kernel versions are compared without pkgrel, so a stock packaging-only update doesn't trigger a rebuild reminder. A custom build already in the local repository but not installed yet counts as up to date.

The content of the last notification is stored in $XDG_STATE_HOME/update-notify (default ~/.local/state/update-notify). Delete it to get the current notification again.
