Main usecase for this is to fully automate ``borg change-passphrase``.
BORG_DISPLAY_PASSPHRASE
When set, use the value to answer the "display the passphrase for verification" question when defining a new passphrase for encrypted repositories.
BORG_EXIT_CODES
When set to "modern", the borg process will return more specific exit codes (rc).
Default is "legacy" and returns rc 2 for all errors, 1 for all warnings, 0 for success.
BORG_HOST_ID
Borg usually computes a host id from the FQDN plus the results of ``uuid.getnode()`` (which usually returns
a unique id based on the MAC address of the network interface. Except if that MAC happens to be all-zero - in
