Why use the AWK, which, BTW, is a terrific language? It does have some overhead/startup costs. I just pegged myself as a 300Mhz P3 user, didn't I?
I'm pretty sure something could be done with sed on the output of ls *.root as well,
[later] Of course
works as well but note the extra separating space.

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.
