just installed openbsd on my chromebook, seems to be working fine!
since it's my first time using openbsd, here are some stuff that i will start to do on my machines after installing openbsd:
enable doas
doas is kinda the equivalent of sudo . to enable it, run cp /etc/examples/doas.conf /etc to copy the doas config file.
disable root account
now that doas is ready, we dont need to root account anymore. to disable it, run usermod -p'*' root to set the root password to * . this will prevent root from log on directly to the machine (with su as an example), but with doas we can run doas sh to get a shell.
install missing firmware for your hardware
maybe your wifi card isn't working? or maybe you can't display any graphical interface? maybe that's because you don't have the firmware for it: here's how to install it:
run doas fw_update -i to see the missing firmwares.
so grab a flash drive, format it in fat filesystem format, go to firmware.openbsd.org , download the missing firmwares, along with the SHA256.sig and index.txt files, and put them on the usb key.
mount the flash drive on openbsd, and run doas fw_update -p *path of flash drive* to install the firmwares from the flash drive.
your missing firmware should not be anymore.
