That was my first reaction but there are places where "hostname" already gives a name that is not "short" at all, without being invoked with "-f". For example, the (virtual) workstation I am typing this message on sits in a $WORK datacenter, where "hostname" gives the same string as "hostname -f", which looks like "git.c.xxxxxx.tld" ("git" is the only part I picked myself for it, "c" is shared by those employee workstations hosted at datacenters, "xxxxxx.tld" is redacted to conceal the real domain name to protect the culprits ;-). I think the most honest answer we can give in the documentation is that we use what gethostname() [*] gives. [References] * https://pubs.opengroup.org/onlinepubs/9699919799/functions/gethostname.html
