LD_RUN_PATH was my thinko -- LD_LIBRARY_PATH was what I was thinking. And while it does affect more than this, if set specifically for the qemu executable e.g. by a script then it need not really affect much. > If we are using the dynamic linker and DT_RUNPATH (which I believe > is in the executable) or the normal paths we WILL NEED proper API > versioning etc.; in this case (in the distro example I pulled out), > an upgrade to qemu making an API change will have different API > versioned libs and these can happily coexist, so no need for directories. I don't believe I ever suggested we're stable, or should even pretend to be so at this point. Install multiple qemu to different trees, and use different paths. Or even use the $ORIGIN prefix, which allows paths relative to the main executable, allowing the installed qemu tree to be moved at its root. r~
