Undocumented --read-environment in ifup/ifdown/ifquery
Clash Royale CLAN TAG#URR8PPP
I read Debian's systemd network startup units and found that
each of ifup/ifdown/ifquery
is run with --read-environment
, but
I cannot find this option in man
. Could any one point to a description of this thing?

These are Debian's tweaks to let SysV init script settings from /etc/default/networking apply to systemd service file.
Namely:
- CONFIGURE_INTERFACES which disables interfaces configuration on boot
if set to "no". - EXCLUDE_INTERFACES, a list of interfaces to exclude from
configuration on boot (shell wildcards available). - VERBOSE set to 'yes' for extra messages.
They are undocumented as internals to the integration of ifupdown into systemd.
source:
Read /etc/default/networking when started from systemd. Closes: #806883
Add an undocumented --read-environment option which will cause the
VERBOSE, CONFIGURE_INTERFACES and EXCLUDE_INTERFACES environment
variables to be read and act in the same way as with ifupdown's SysV
init script. This allows the use of
EnvironmentFile=-/etc/default/networking in the systemd service file.
