Impossible to do. Nothing at all can be done without knowledge. |
19 |
|
20 |
IMO a better question is: How hard is it, to get proper |
21 |
knowledge? |
22 |
|
23 |
Answer: Easy, thanks to the excellent LVM howto. See |

Very basic hint: Make your filesystems as small as possible and |
30 |
enlarge them, when required. This means, that you'd start out |
31 |
with a lot of unallocated space. |

Hm. Those are IMO too large. Generally, I'd make the filesystems |
54 |
so large, that they are about 80% filled. |

As I've said often before: I'd use filesystems for /, /var, /opt, |
59 |
/boot, /usr and /home. And actually I also use seperate filesystems |
60 |
for Gentoo stuff. |
