Yes, because he'd give the (IMO *extremely* *bad*) advice to use |
| 33 |
just one huge filesystem for everything. |
| 34 |
|
| 35 |
I very much disagree with that. IMO, even on home systems it makes |
| 36 |
a lot of sense to use multiple file systems. |

It doesn't have anything to do with LVM. |
| 41 |
|

You're mentioning a "problem" of LVM: With LVM, the Logical Volumes, |
| 43 |
and thus the filesystems on top of those LVs can be fragmented (and |
| 44 |
very often will be). This happens, when a LV will be resized. Reason: |
| 45 |
Suppose two LVs are created. Those 2 LVs are adjacent. Then the 1st |
| 46 |
LV (at the beginning of the VG) is to be extended (made bigger). This |
| 47 |
will cause the first part of the 1st LV to be in front of the 2nd |
| 48 |
LV and the 2nd part of the 1st LV will be after the 2nd LV. |
