Correct for isolation, slow for heavy shared deps (qt5, boost). The + optional package cache (see above) mitigates this: a dep is installed from + cache when its version is unchanged instead of rebuilt. The named target + always builds fresh regardless. - **overlayfs sharp edges.** A build that fails ONLY in the overlay but works on bare 15.0 is more likely an overlayfs quirk (rename/whiteout) than a real build bug. Noted near the build step in the source. |
