I have OpenBSD running on a Raspberry Pi 3B+ as a home server hosting this wiki. I really enjoy the secure-by-default stance, quality documentation, and all the nice things they've added to the OS to help applications be more secure. It's quite well-suited for server applications.
I used to run OpenBSD on my Lenovo ThinkPad X250 as a daily driver from 6.7 through 7.1, but something broke in the X windows system during the upgrade to 7.1 and I couldn't be bothered to fix it, so that ThinkPad runs Manjaro Linux these days. The Spectre/Meltdown mitigations and disabled Bluetooth are fantastic from a security standpoint, but don't lend themselves well to convenient computing like running a Linux distro does.
- update system:
syspatch; pkg_add -u
- search for a package:
pkg_info -Q ripgrep
- install a package:
- search manpages for "unveil" with

- mount sd card in
mount.exfat /dev/sd1i /mnt/sd
- mount thumbdrive in OpenBSD:
mount /dev/sd1i /mnt/thumbdrive
- burn image to thumbdrive sd1 (verify with
dmesg) in OpenBSD:
dd if=some.img of=/dev/rsd1c
- execute a command over ssh as if it were a local shell:
ksh -l -c your_command
- brother printer driver using cups on localhost and brlaser: http://localhost:631/printers/
- brother printer queue is at: http://printer_ip_address:631/ipp
- ksh has a user process data limit that can keep qemu from spawning VMs. You
can view ksh's limits with
ulimit -aand adjust the data limit to 4 GB with
ulimit -d 4194304.
- specify compiler for GNU configure scripts:
- Free Pascal Compiler installation.
- Web log analysis using GoAccess.
