// BSD sysexits.h (which is also in GNU libc) defines several exit
// codes in the range 64-78. These are typically used in the context

// mail systems such as Postfix to interpret the local(8) delivery
// agent's exit status. Using these for service exit codes isn't
// recommended by LSB (which says they are in the range reserved for
// future LSB use) or by daemon(7). However, they are used in
// practice, and are recognized by systemd.
