Sorry, ianap, but I do know that this kind of thing has never happened |
24 |
to me in my 8+ years of running this old system with a separate /usr |
25 |
*without* an initramfs... |
26 |
|
27 |
So, the bottom line is, obviously (to me at least), there are a lot more |
28 |
things that can go wrong when an initramfs is involved, that simply |
29 |
don't or can't happen otherwise. |

Sorry, I don't see where he said that this system was running on a VM... |
41 |
or did you mean where he had / on an *LVM* partition - which, again, he |
42 |
did not say he had. |
