My setup: TC 2.4.1 in Virtual Box, I have a VM set up just for testing which I boot from the iso and a small virtual hard drive to store possible extensions.
Testing procedure: Boot with clean hd, no extensions or backup, used bootcode tce=hda1 to setup tce dir. "Installed" hal.tczl (only because it depends on the 2 libs in question) and verified extensions were listed in tcz2ram.lst. Rebooted using bootcode "showapps". Booting completed, successfully loading all extensions even though the libuuid version error does appear.
I removed tcz2ram.lst and rebooted again using bootcode "showapps". Booting completes unsuccessfully loading all extensions. First error seen during extension loading is pertaining to the dbus error discussed in another thread, which does not cause the extension loading to abort (I guess because the error stems from its post-install script). Second error is the libuuid version one which does cause extension loading to abort, not loading the rest of the extensions in tce/.
Conclusion: "Installing" libuuid does allow all extensions to be loaded, but still shows the error. "Mounting" libuuid causes extension loading to abort and error to show.
