I just received a new laptop (dell 6430s) with a 256GB SSD and naturally |
2 |
want to install gentoo. I have installed gentoo several times but this |
3 |
is my first with an SSD. |
4 |
|
5 |
Dell configures a small first partition and places windows on two other |
6 |
partitions (one small; the other the rest of the disk). |
7 |
|
8 |
I reinstalled windows shrinking the large partition very considerably (I |
9 |
essentially never use the dell partition or windows; but they are |
10 |
convenient to have if you need service from dell). |
11 |
|
12 |
In my current system, I have |
13 |
|
14 |
/root "native partition" |
15 |
/usr lvm2 |
16 |
/local lvm2 |
17 |
/var lvm2 |
18 |
/tmp lvm2 |
19 |
/opt lvm2 |
20 |
/a lvm2 |
21 |
|
22 |
My plan is to have root+usr on one "native partition" (to appease the |
23 |
oracle at udev) and the rest on lvm2 as in my current configuration. |
24 |
|
25 |
Although I will install dracut and perhaps try/use it, I do not want my |
26 |
partitioning scheme to *force* me to use it. I believe combining root |
27 |
and usr (off lvm2) will accomplish this goal. |
28 |
|
29 |
I was not surprised to see that the latest manual has root+usr combined, |
30 |
but was surprised that they specify an additional small /boot partition. |
31 |
I had thought that went out of favor a few years ago. Is it back |
32 |
because of the root+usr merge? Do people here recommend a separate |
33 |
/boot? |
34 |
|
35 |
I know that it is important to have ssd partitions well aligned. It |
36 |
appears that fdisk is doing this automatically (see below). Does the |
37 |
following partitioning seem OK? |
