On every boot, the following error is logged during the initrd phase:
'/usr/lib/systemd/system-generators/dracut-crypt-generator' failed with exit status 2.
This occurs on systems with no encrypted volumes and no /etc/crypttab.

Root Cause

The generator script usr/lib/systemd/system-generators/dracut-crypt-generator (installed inside the initramfs by the 90crypt dracut module) uses return statements to exit early:

[ -e /etc/crypttab ] || return 0

systemd executes generators as standalone processes, not sourced shell scripts. When return is used outside of a function in a non-sourced script, the shell treats it as an error and exits with code 2. systemd then logs this as a generator failure.
The script has multiple return statements that should be exit.

Reproducible: Always

Steps to Reproduce:
1. Boot any Fedora 45 aarch64 (or likely any arch) system with dracut 111-1.fc45
2. The system must not have encrypted volumes (no /etc/crypttab)
3. Check the journal: journalctl -b | grep dracut-crypt-generator
Actual Results:
Errors in boot log:
(gene[NNN]: '/usr/lib/systemd/system-generators/dracut-crypt-generator' failed with exit status 2.

Expected Results:
No error. The generator should exit cleanly with code 0 when there is nothing to do.

Additional Information:
- dracut: 111-1.fc45
- Kernel: 7.2.0-0.rc6.260807gf9a2394a2348.52.fc45.aarch64
- Reproduced on: GNOME Workstation, KDE Plasma, Xfce, Minimal -- all Fedora 45 aarch64 spins on Raspberry Pi 4
- Not present in: dracut 109-7.fc45 (earlier boots did not show this error)
- Impact: Cosmetic only -- boot continues normally. But it creates unnecessary noise in every boot log.
