Is it required that the _exact_ _same_ _data_ will be regenerated? This is not the case with most users of /var/cache (like ccache for example). They only regenerate what is needed so the application continues to work properly. The ebuilds that are needed for portage functioning are saved to /var/db/pkg already. squid cache would be another example, or just about every other Linux distro's package manager. > What about /usr/portage/licenses, for example?
