        This is another UN*X I really like.
       
        When I read OpenBSD removed Linux Emulation and added a 2038
        workaround for i386.  I decided to give it a go, I was not
        disappointed.  I believe I started using it around version 6.3.
        Personally, I think Linux Emulation that other BSDs have only
        creates issues, but I believe the other BSDs uses a module
        for that Emulation, so I should be easy enough to disable.
       
        I had an old Thinkpad (R51e) and I decided to put OpenBSD
        on it for a test spin, it worked and still works great.
        From there it found its way to the other old Laptop I have.

        As I used it I learned about all the security enhancements
        and realised this would make a great home system.
       
        I also really like the idea of pledge and unveil, I believe
        these are a much better solution than the various containers
        Linux is now pushing.  Because of that, I have put these calls
        in most of my utilities I have in my repo.

        For development, when I took some work applications and
        compiled and tested it on OpenBSD, many issues were identified.
        These crashed due to various issues where Linux and AIX would
        happily continue running.  Of course I corrected the problems.
       
        I use OpenBSD on a Thinkpad T420, I would use it on the newer
        W541, but OpenBSD heats up the nVidia GPU in the lower left
        hand corner.  It does know enough to ignore nVidia and use
        the Integrated Intel GPU, but the nVidia GPU gets very hot.
       
        I general, OpenBSD runs hotter than the other Operating Systems.
        If not for that, it would be my main driver.  IIRC, the heat
        issues started around release 6.8.  Right now I am hoping
        these issues are solved in newer releases.
       
        With that said, Port obsdfreq helps a lot with the heat issue,
        but not with the nVidia Issue on the W541.  So using obsdfreq
        Solene created keeps the CPU Temp reasonable. This is what I
        have in rc.conf.local to start obsdfreq:
       
           obsdfreqd_flags=-m 75,55 -l 0,0 -T 70,60 -r 50 -s 3 -t 3000
       
        I use Slackware on the W541, OpenBSD on a Thinkpad T420.
        So, I consider the T420 w/OpenBSD to be my "travel" laptop.
        When I travel I use OpenBSD on it because I believe its Full
        Disk Encryption is much better than Linux LUKS.
       
        Note, I checked with ##ibmthinkpad on Librachat, due to the
        nVidia heat issue, they said best to avoid using OpenBSD on
        the W541 until it is fixed or you find a workaround :(  That
        is a bit disappointing.
