Uh - unless you don't have enough space on one drive I'd mirror root - |
| 9 |
not stripe it. Ditto for boot - if you are willing to do raid you can |
| 10 |
boot a mirrored /boot just fine. |

Well, you could do that, but /usr and /var can go on LVM instead, and |
| 20 |
that will save you a LOT of space on /. You can then resize /usr and |
| 21 |
/var at will. I like to keep /var on a separate filesystem so that it |
| 22 |
doesn't tend to fragment everything else. |

/proc and /sys don't use any real disk space - they're just mountpoints. |
| 28 |
I have a 1GB root and it is only 30% full - but again I put usr and var |
| 29 |
elsewhere. |

Well, I won't start a big discussion on this here (look in the archives |
| 38 |
for some good discussion on this topic). The short version is that |
| 39 |
there are potential benefits for having swap even if you have 200GB of |
| 40 |
RAM and only run 50MB worth of applications (the returns probably do go |
| 41 |
away if you actually have more RAM than total storage). |

You can just copy files from a live CD. Actually, I've copied them from |
| 49 |
a running system - granted in single-user mode for the more critical |
| 50 |
stuff. I just used cp -a without much issue, but there might be some |
| 51 |
advantages to using tar (it might handle stuff like mountpoints and hard |
| 52 |
links and device nodes and FIFOs and stuff like that better - I'm not |
| 53 |
sure about that offhand). |
| 54 |
|
| 55 |
If you copy and leave the original data intact it is pretty easy to |
| 56 |
recover. I just moved data partition by partition and remounted on my |
| 57 |
existing root as I went along - slowly transforming my existing disk |
| 58 |
arrangement into my future setup. I didn't have too much downtime |
| 59 |
except for the final cutover of the root filesystem. |
