Needrestart checks which daemons need to be restarted after library upgrades. It is inspired by checkrestart from the debian-goodies package.

Features: - supports (but does not require) systemd - binary blacklisting (i.e. display managers) - tries to detect required restarts of interpreter based daemons (supports Java, Perl, Python, Ruby) - tries to detect required restarts of containers (docker, LXC) - tries to detect pending kernel upgrades - tries to detect pending microcode upgrades for Intel CPUs - could be used as nagios check_command - fully integrated into apt/dpkg using hooks
