Description Renaud Métrich 2021-07-09 12:21:44 UTC 
Description of problem:

Nowadays it's hard to troubleshoot clevis issue happening early during boot in the initramfs phase, because even with rd.debug, clevis scripts run blindly.
This would definitely help troubleshooting when something goes wrong (PCR changes or Tang issue for example).

This can be done on RHEL/Fedora using the following snippet at the beginning of /usr/bin/clevis-luks-common-functions:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
enable_debugging() {
    # Automatically enable debugging if in initramfs phase and rd.debug
    if [ -e /usr/lib/dracut-lib.sh ]; then
        local bashopts=$-
        # Because dracut is loosely written, disable hardening options temporarily
        [[ $bashopts != *u* ]] || set +u
        [[ $bashopts != *e* ]] || set +e
        . /usr/lib/dracut-lib.sh
        [[ $bashopts != *u* ]] || set -u
        [[ $bashopts != *e* ]] || set -e
    fi
}
