This sounds encouraging. My disk is less than half full so space is not |
| 7 |
an issue. |

Question. For me, / is actually /dev/sda5 (sda4 is the extended |
| 12 |
partition, the three in front are one dell's special, and two for |
| 13 |
windows, the latter only used when contacting dell for diagnostics). |
| 14 |
But I think this difference is not material. |

Question. /dev/sda7 is LVM and that is used for /usr, /local, et al. |
| 25 |
How do I move an LVM partition? I could make plain partitions and just |
| 26 |
copy /usr, /opt, et al., each to a separate partition. Is that the way? |

/ is ext3, which I believe can be extended live. Or do you recommend |
| 32 |
using a gentoo install CD (or equivalent)? |

This part seems straight forward and not scary since I still would have |
| 40 |
the newly created and copied /usr, /opt, et al. partitions in case |
| 41 |
something goes wrong. |
| 42 |
|
| 43 |
So the result would be |
| 44 |
|
| 45 |
/ (including /usr) on one partition (not LVM) |
| 46 |
/local, /opt et al., each as separate LVs on my recreated LVM partition |
| 47 |
|
| 48 |
I believe this is one of the configurations others have adopted, which I |
| 49 |
consider a plus. The other favored configuration is to keep the current |
| 50 |
partition scheme and use an initramfs via genkernel, dracut, or Neil's |
| 51 |
"in kernel config" soln. |
| 52 |
|
| 53 |
I would suspect there are second order improvements such as moving |
| 54 |
/usr/portage and /usr/src to LVM with symlinks left behind in /usr, but |
| 55 |
I am now just concerned to see if I have the basic plan correct. |
| 56 |
Have I? |
