Are rc scripts executed serially or all at the same time. Is there a way to see this happen? A log file or the syslogd?

hi,
If we place Sxx (startup script) and Kxx(shutdown script) in /etc/rc.d/rc2.d,then it would start and stop automatically(assume they are linked to other script that actually starts/stops).

dracut-shutdown.service
DRACUT-SHUTDOWN.S(8) dracut DRACUT-SHUTDOWN.S(8)NAME
dracut-shutdown.service - unpack the initramfs to /run/initramfs
SYNOPSIS
dracut-shutdown.service
DESCRIPTION
This service unpacks the initramfs image to /run/initramfs. systemd pivots into /run/initramfs at shutdown, so the root filesytem can be
safely unmounted.
The following steps are executed during a shutdown:
o systemd switches to the shutdown.target
o systemd starts /lib/systemd/system/shutdown.target.wants/dracut-shutdown.service
o dracut-shutdown.service executes /usr/lib/dracut/dracut-initramfs-restore which unpacks the initramfs to /run/initramfs
o systemd finishes shutdown.target
o systemd kills all processes
o systemd tries to unmount everything and mounts the remaining read-only
o systemd checks, if there is a /run/initramfs/shutdown executable
o if yes, it does a pivot_root to /run/initramfs and executes ./shutdown. The old root is then mounted on /oldroot.
/usr/lib/dracut/modules.d/99shutdown/shutdown.sh is the shutdown executable.
o shutdown will try to umount every /oldroot mount and calls the various shutdown hooks from the dracut modules
This ensures, that all devices are disassembled and unmounted cleanly.
To debug the shutdown process, you can get a shell in the shutdown procedure by injecting "rd.break=pre-shutdown rd.shell" or
"rd.break=shutdown rd.shell".
# mkdir -p /run/initramfs/etc/cmdline.d
# echo "rd.break=pre-shutdown rd.shell" > /run/initramfs/etc/cmdline.d/debug.conf
# touch /run/initramfs/.need_shutdown
