1. Prepare a filesystem for a new root

• newfs a filesystem and mount and cd there

2. Fill the new root

• Extract baseXX.tgz to ${root}
  • doas tar xzpf baseXX.tgz -C ${root}
• Extract ${root}/var/sysmerge/etc.tgz
  • doas tar xzpf ${root}/var/sysmerge/etc.tgz -C ${root}
• Copy the kernel to ${root}/bsd

3. Configure

• ( cd ${root}/dev && sh MAKEDEV all )

Serial console

Forwarding as telnet

serial0.present = "TRUE"
serial0.fileType = "network"
serial0.fileName = "telnet://127.0.0.1:10001"
serial0.startConnected = "TRUE"

This worked for VMware Fusion 5. Should also work on VMware Workstation.

Basic

• Don't try "unprivileged" build from start.
  • First do cross-dirs/cross-tools/cross-distrib as root (sudo).
  • Then change owner/mode of obj directories. This will make development easier.
• Always use cross build (for development).
  • Otherwise you'll overwrite your /usr/include during build.
  • Cross build can't make release on OpenBSD, unfortunately (because of gnu/, where Makefile.bsd-wrapper is used). So cross build is only for development.

Tips

• Phony is evil
• Keep makefiles contain only dependency
• Don't define -DXXX in makefiles (makefile changes output content)
• If do so, output has to depend on makefile itself (evil road...)
• How to pass vars to sub-make ("VAR=val make" vs. "env VAR=val make" vs. "make VAR=val")
• Evaluation order (variables are evaluated at statements like .if, .for, ...)
• .SUFFIXES (inference rule) is GREAT
• Don't treat directories as input/output
