General rule(s) for subvolumes as I learned them: |
| 16 |
|
| 17 |
* create them if you want to separate things logically |
| 18 |
|
| 19 |
* use them if you want to use specific settings/parameters for specific |
| 20 |
directories/subvols: for example compression, quotas ... |
| 21 |
|
| 22 |
* use them if you want to use snapshots. A (btrfs-)snapshot is always |
| 23 |
based on a subvolume so if you want to create snapshots for particular |
| 24 |
areas you have to set them up as subvolumes in advance. |
| 25 |
|
| 26 |
Splitting it into /boot, /, /home and maybe /distfiles (no compression |
| 27 |
here ... ?) is a usual approach. Keeping it as simple as possible in the |
| 28 |
start is a good idea. You can always add subvols later ... and move |
| 29 |
things over ... |

As I see the howto and the steps about booting: |

|
| 36 |
I didn't do it that way but used dracut for the initrd ... the |
| 37 |
ml-archives have some threads around learning this (combined with |
| 38 |
systemd and LVM stuff back then I spent quite some time ...). |
