# as a default: gccXX.X-tagged tarballs need a libstdc++ new enough to match,
# and Ubuntu's base image keeps libstdc++6 updated while RHEL/Rocky pin their
# system toolchain for the OS lifetime.

# SideFX Labs, baked in rather than installed through Houdini's own in-app
# package installer. That installer writes into $HOUDINI_USER_PREF_DIR
# (under $HOME), which distrobox bind-mounts from the host over whatever the
# image ships there — so anything baked in under $HOME would just be
# shadowed at runtime, and doing it live means every container needs its own
# git-clone/download at first launch (this is also almost certainly the
# actual source of the "no such file or directory": the installer shells out
# to `git`, which this image never installed).
# $HFS/packages is a package-search path Houdini scans unconditionally,
# independent of $HOME (see `houdini/ref/plugins.html` in SideFX's docs), so
# drop the official package descriptor + the Labs tree there untouched: the
# descriptor's default `$HOUDINI_PACKAGE_PATH/SideFXLabs22.0` already
# resolves correctly since HOUDINI_PACKAGE_PATH is just "wherever this json
# file lives".
