I stumbled upon the bsdutils package in Debian. The description says:
This package contains the bare minimum of BSD utilities needed for a Debian system: logger, renice, script, scriptlive, scriptreplay and wall. The remaining standard BSD utilities are provided by bsdextrautils.
Similarly, the description of bsdmainutils also mention BSD:
This package contains lots of small programs many people expect to find when they use a BSD-style Unix system.
I was surprised to see that these packages relates to BSD, in the context of a Linux system.
Do these packages use some code from BSD? What is a BSD-style Unix system?
