Yep, that's exactly right. The # prompt reminds you that you are root; whether you logged in as root or su'd up to root.

Other users get the $ prompt.

You can modify your prompt to 'root@<nodename>' which is even better for reminding you what rights you have.

Many administrators spend their time switching between accounts, and/or su'ing to root to do specific tasks.

On most flavors of Unix/Linux the root user by-passes ALL security so one mistake as root can blow up the system whereas other users will get caught by security if the try to do something stupid.

The # reminds you that you are root (ie, god) and anything you say goes; no questions asked; literally!!!!

If you're a sysadmin with multiple systems on your network setting a prompt of 'root@<nodename>' also reminds you which system you are on as you move about your different systems.

systemd-volatile-root.service

SYSTEMD-VOLATILE-ROOT.SERVICE(8)			   systemd-volatile-root.service			  SYSTEMD-VOLATILE-ROOT.SERVICE(8)

NAME

       systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile

SYNOPSIS

       systemd-volatile-root.service

       /lib/systemd/systemd-volatile-root

DESCRIPTION

       systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the
       original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in
       /etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown,
       enabling fully stateless systems.

       This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command
       line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this
       service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile.
