Few files are left, the hardened patch should update the appropriate Makefile rules too, or ? : | Code: | tor-relay /usr/src # ls -lR linux-3.17.3-hardened

| what's the difference between rm -rf linux-X.X.X then re-emerging and make mproper? Granted you saved .config first. |

| The former generates a lot of unnecessary writes to the disk. For some SSD users, avoiding unnecessary writes can be valuable for performance or drive lifetime reasons. |

Erm, why "make mrproper" after a fresh install/re-emerge ? |

I meant if make mrproper is failing. Do this.
Save .config somewhere else.
rm -rf /usr/src/linux-xxx
emerge gentoo-sources
I doubt doing this ONCE will dramatically reduce the life of a SSD to such an extent of being a mental concern interfering with your daily life. Besides TRIM takes care of ware out. |

| Yes, the unnecessary writes are not a major problem for a quality SSD if done once. I prefer to stop SSD-unfriendly practises at the source, before they become widely quoted or frequently practised. TRIM will reduce the long term negative impact by reclassifying the cells as free so that they are not unnecessarily preserved, but it does not undo the write. |
