# Small daemon to identify this machine to the OpenVPN server

# SEE /usr/bin/iiab-support for local_vars.yml var extraction explanation
# Empty string, worst case, e.g. whether var is set to "" (or not set at all!)
# EMULATE ANSIBLE: but additionally Force Empty String Where Nec, e.g. whether
# local_vars.yml sets openvpn_handle to "" (or worst case null, or not at all!)

# Change all spaces to underscores -- same as "s/ /_/g"
# /usr/bin/iiab-support emulates this, to help folks understand
HANDLE=${HANDLE// /_}
# ALSO GO 1 STEP FURTHER THAN ANSIBLE: convert remaining spaces to underscores,
# for OpenVPN server. iiab-support emulates this, to help folks understand.
HANDLE=${HANDLE// /_} # Same as "s/ /_/g"
# Likewise empty string is the worst case, e.g. if file doesn't exist.
# If handle is "", OpenVPN server tries to use the 1st 6 chars of UUID
# If $HANDLE is "", OpenVPN server tries to use the 1st 6 chars of UUID,
# e.g. e1a3d4 from e1a3d4e2-2d1a-4f37-9ba0-e836d7c8e3ca
