## Pre-install the fundamental packages
## Install Python SSWSDK (lldpsyncd dependancy)
## Install LLDP Sync Daemon
## Note: dpkg_apt function has the benefit to detect missing .deb file
## Clean up

## There is a known bug: agetty processes at 100% cpu
## When:
##   1. running container in --privileged mode
##   2. container runs /sbin/init
## ref: https://github.com/docker/docker/issues/4040
## Temporary solution:
##   Disable tty services permanently
RUN systemctl --no-pager list-unit-files --type=service | grep getty | awk '{print $1}' | xargs systemctl mask
## Note: getty@.service in last grep output will not mask below cases
RUN systemctl mask getty@tty1.service

## Specify init as CMD to enable systemd
## Note: don't provide ENTRYPOINT at the same time
CMD ["/sbin/init"]
