Explanation of "total" field in "ls -l" command output
When I do a listing in one particular directory (ls -al) I get:
total 43456
drwxrwxrwx 2 root root 4096
drwxrwxrwx 3 root root 4096
-rwxrwxr-x 1 nobody nobody 3701594
-rwxrwxr-x 1 nobody nobody 3108510
-rwxrwxr-x 1 nobody nobody 3070580
-rwxrwxr-x 1 nobody nobody 3099733
-rwxrwxr-x 1 nobody nobody 2602570
-rwxrwxr-x 1 nobody nobody 3184369
-rwxrwxr-x 1 nobody nobody 2903501
-rwxrwxr-x 1 nobody nobody 2981555
-rwxrwxr-x 1 nobody nobody 2063089
-rwxrwxr-x 1 nobody nobody 2892216
-rwxrwxr-x 1 nobody nobody 3057414
-rwxrwxr-x 1 nobody nobody 4142959
-rwxrwxr-x 1 nobody nobody 3906603
-rwxrwxr-x 1 nobody nobody 3694698
What does the "total" field in the above output mean?

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.
