Is it required that the _exact_ _same_ _data_ will be regenerated? This |
| 7 |
is not the case with most users of /var/cache (like ccache for example). |
| 8 |
They only regenerate what is needed so the application continues to work |
| 9 |
properly. The ebuilds that are needed for portage functioning are saved |
| 10 |
to /var/db/pkg already. |

|
| 12 |
squid cache would be another example, or just about every other Linux |
| 13 |
distro's package manager. |

They are not required for functioning of the system, and a sync will |
| 20 |
restore them. |
