finit 4.0~rc3-1 (amd64 binary) in ubuntu impish

 Finit is a simple alternative to SysV init and systemd, reverse engineered from
 the EeePC fastinit ten years ago by Claudio Matsuoka - "gaps filled with frog
 DNA ..."
 .
 Finit supports runlevels, process monitoring, and starting services on demand
 using the built-in inetd, or by triggering a condition. E.g., "don't start this
 service until basic networking is available", or "wait until syslogd has
 started".
