# PKGBUILD — autofs (ansipa self-hosted build)
#
# WHY THIS EXISTS:
#   The AUR `autofs` package is a hard dependency of the AUR `freeipa-client`
#   package (which ansipa needs to enroll Arch hosts into FreeIPA). As of the
#   autofs 5.2.0 upstream release, the kernel.org mirror pruned the
#   autofs-5.1.9.tar.xz tarball that the AUR PKGBUILD pins, so the AUR autofs
#   build fails with a 404 on its source — which in turn makes freeipa-client
#   (and therefore every Arch FreeIPA enrollment) impossible to install.
#
#   Rather than depend on that fragile, currently-broken tarball URL, this
#   PKGBUILD builds autofs from the upstream git repository pinned to a fixed
#   commit on the 5.1.9 maintenance series. That commit already contains the
#   upstream fix for "incompatible function pointer types in cyrus-sasl module"
#   (commit b7ff971b) that GCC 14+ requires, so we do not need the separate
#   downstream compiler patch the AUR fetched from the (also fragile) mirror.
#
#   freeipa-enroll.sh builds and installs this package before invoking the AUR
#   helper for freeipa-client, so the dependency is already satisfied and the
#   broken AUR autofs is never touched.
#
# Based on the AUR autofs PKGBUILD (maintainers: Alexander Jacocks, Hyacinthe
# Cartiaux et al.), reworked to build from git.
