# OpenBSD ships X.Org (xenocara) in the base system under /usr/X11R6, so the X
# libraries, the protocol headers and their pkg-config files are already
# present — only the build tooling (and a few libs not in base) come from
# packages via pkg_add. The vmactions OpenBSD image pre-configures the package
# mirror (installurl / PKG_PATH), so a plain pkg_add resolves.

# Retry a command a few times with linear backoff; package mirrors flake
# transiently and a single network hiccup must not abort the whole CI run.
