On Darwin, launchd may attempt to start agents before the Nix store is
mounted and available. This leads to failures when the agent's executable
or arguments reside in the Nix store.
This change wraps the agent's command in a shell script that uses
/bin/wait4path to ensure /nix/store is ready before executing the
original program. It also ensures that ProgramArguments are correctly
escaped and concatenated.
Instead of having to manually stub packages that should not be
downloaded we instead automatically stub all packages (except a small
list of whitelisted ones). Tests can re-introduce the real package by
using the `realPkgs` module argument.
This reflects a systemd service sample file change made in borgmatic
1.7.6, commit 2e9f70d49647d47fb4ca05f428c592b0e4319544:
When backing up a machine with a monitor using logind to control
idle timeout and things like DPMS, borgmatic can block the screen
from turning on/off with systemd-inhibit. This is because by
default systemd-inhibit will block
"idle:sleep:shutdown". Borgmatic does not need to care about idle,
only about suspend and shutdown. So, add an explicit `--what` flag
for what borgmatic should inhibit.
For more information see systemd-inhibit(1).
