arch_update

Arch Linux system update script

Install

git clone https://git.streifling.com/jason/arch_update.git ~/src/arch_update
ln -s ~/src/arch_update/arch_update ~/.local/bin/

Nothing else is needed; a config is optional.

Config

Settings are read from ~/.config/arch_update/config, see config.example.

Hooks

After the system update and before the post snapshot, every executable file in hooks.d/ of this repository and in ~/.config/arch_update/hooks.d/ runs in alphabetical order. A failing hook is reported, the remaining hooks still run. Variables from the config are available as environment variables.

Every hook checks itself whether it has work on this machine. A file in ~/.config/arch_update/hooks.d/ replaces the repository hook of the same name, so an empty file disables it:

mkdir -p ~/.config/arch_update/hooks.d
touch ~/.config/arch_update/hooks.d/40-nvim-vim

Pre hooks

pre-hooks.d/ works the same way, but runs before the pre snapshot, so the snapshot holds its output. If a pre hook fails, the update only continues after confirmation. pre-hooks.d/10-db-backup dumps every PostgreSQL server on the host and in the containers of DOCKER_COMPOSES into DB_BACKUP_DIR and keeps the newest DB_BACKUP_KEEP runs.

Docker compose

Without DOCKER_COMPOSES in the config, every running compose project is updated and backed up.
