OpenBSD 7.0 released! #Unix #OpenBSD @openbsd


OpenBSD 7.0 was recently released. This is their 51st release, providing significant improvements, including new features, in nearly all areas of the system.

New 7.0 release highlights

  • doas is now asking password again on failure
  • better hardware support (AMD, docks)
  • faster (un)hibernate (ZZZ)
  • faster WiFi speed
  • xterm has unveil
  • base gcc removed on amd64
  • bsd-reconfig to have a KARL compatible modified kernel
  • new dhcpleased and resolvd superseding dhclient (no configuration change required)
  • performance improvements for heavy loads on many cores
  • Firefox isn’t available anymore on i386 (), seamonkey is a fine alternative
  • Much work on compatibility for Apple M1 (still not ready for prime time)

OpenBSD 7.0 comes with a new utility named timeout to run a command and stop it after an user defined time. The  is available for full information. While it was possible to achieve this in shell using a child process sleeping for some time and stopping the main process if it wasn’t finished yet, timeout makes this job very easy. One simple real world use case would be a lazy site-to-site synchronization using a rsync job run every night when the Internet uplink can be fully used and stopped right before people will need the network. Such a scenario can be done with timeout 8h rsync -a /data/ remote:/data/ and started from a cron job at 00h00. In this case rsync would run at midnight and timeout would stop it at 8h00 if the job is not finished.
