Intended to get to the next level of fine-tuning needed with more discrete debug settings:

• https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html

general debugging

debug ignore_loglevel print_fatal_signals=1 printk.time=1 logo.nologo panic=0 log_buf_len=10M

systemd debug for service failures

systemd.log_level=debug systemd.log_target=kmsg

delay each printk during boot 1s (readability)

boot_delay=1000

suspected SElinux / AppArmor issues

selinux=0 apparmor=0 enforcing=0

break into init

break=y S
