I did that some time ago in a simple-minded fashion, but I've had to revise |
| 7 |
my layout somewhat. I had an ext3 partition solely for /usr/portage, and it |
| 8 |
was mounted on that node, but every emerge --sync deleted the /lost+found |
| 9 |
directory. I don't know how serious that is, but of course no-one likes to |
| 10 |
have damaged file systems on their boxes, so I used tune2fs -c to set the |
| 11 |
mount count to 1 so that it was repaired every time the box booted, but that |
| 12 |
was taking too long and it was only a palliative anyway. The solution was |
| 13 |
easy, though of course I didn't see it at first! I only had to point |
| 14 |
/usr/portage to /usr-bits/portage (/usr-bits being the mount point of the |
| 15 |
partition) instead of mounting the partition directly in place. |

A word of caution for anyone considering adopting Duncan's scheme without |
| 18 |
much thought: what he says is certainly good sense, but don't go copying him |
| 19 |
if you're just splitting out bits of the file system that can be made common |
| 20 |
to different running systems. I spent half of last night exploring some of |
| 21 |
the snags! My aim was to separate some large slabs of files into their own |
| 22 |
partitions and mount those partitions on whichever system I was booting. I |
| 23 |
have four Linux systems multibooting on this box, and it seems tidy to find |
| 24 |
common areas and treat them as such. |

Don't combine systems' /var/log directories - you will end up with deeply |
| 27 |
troubled emerge.log and PORT_LOGDIR records. |

Don't combine systems' /usr/src directories. It won't do much harm, but the |
| 30 |
records of which kernel version is installed in each system will cause |
| 31 |
overwriting anyway, thus spoiling the idea, especially if you have |
| 32 |
USE=symlink for gentoo-sources. |
| 33 |
|
| 34 |
I'm not yet sure of the wisdom of combining /var/tmp from different systems: |
| 35 |
I haven't yet sorted out the consequences for the portage work directories. |
| 36 |
Watch this space. |

Apologies if I'm not making much sense today - blame the loss of sleep and |
| 39 |
the head cold that probably caused it :-( |
