The machine needs a full rebuild just to "freshen" it up. Current install is |
| 25 |
going on 6-7+ years, at least three different motherboard/CPU cycles, and the |
| 26 |
SATA drives are pushing 8+ years old at this point in that machine. The same |
| 27 |
drives were previously in my desktop machine between ~2006-2008, so they've had |
| 28 |
a *great* run for spinning rust. I've got new'ish replacement drives and a new |
| 29 |
drive bay recently arrived, so the grsecurity mess was the straw that broke the |
| 30 |
proverbial camel's back. |
| 31 |
|
| 32 |
Just a matter of getting the needed downtime to move data off, |
| 33 |
rebuild/reinstall everything, move stuff back, and check for broken bits. |
| 34 |
Until then, I wasn't sure if switching to gentoo-sources would have any |
| 35 |
side-effects with the hardened userland to get to a newer kernel. |
