There are many ways to do this, but here's one. Make sure you
don't run
ls -a > file_list
or there'll be trouble with rm -rf Smilie

Code:
# ls -l
total 12
drwxr-xr-x  2 root root 4096 Apr 10 16:04 dir_1
drwxr-xr-x  2 root root 4096 Apr 10 16:04 dir_2
drwxr-xr-x  2 root root 4096 Apr 10 16:04 dir_3
-rw-r--r--  1 root root    0 Apr 10 16:02 file_1
-rw-r--r--  1 root root    0 Apr 10 16:02 file_2
-rw-r--r--  1 root root    0 Apr 10 16:02 file_3
# ls > file_list
# while read file; do
>   [[ -d "${file}" ]] && rm -rf ${file}
> done < ./file_list
# ls -l
total 4
-rw-r--r--  1 root root  0 Apr 10 16:02 file_1
-rw-r--r--  1 root root  0 Apr 10 16:02 file_2
-rw-r--r--  1 root root  0 Apr 10 16:02 file_3

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. SEE ALSO
