There's another approach with bind mounts to reduce wasted space. The |
| 14 |
following example is not a joke (notwithstanding the opinions of some |
| 15 |
posters here <g>). I used a 500 megabyte / partition, playing it safe |
| 16 |
because it was my first try, but I could've gotten away with 200 megs. |

Here's what "fdisk -l" and "df" show... |

I create empty /opt /tmp /usr and /var directories in the 500 meg main |
| 41 |
partition (sda5). Except for swap, the rest of the drive is allocated |
| 42 |
to sda7, which is mounted as /home. I create /home/bindmounts and then |
| 43 |
/home/bindmounts/opt /home/bindmounts/tmp /home/bindmounts/usr and |
| 44 |
/home/bindmounts/var. Then I bindmount them to their equivalants on the |
| 45 |
/ partition. I have a script to set up the correct permissions. The |
| 46 |
result is that you can run with a 200 meg main partition, without using |
| 47 |
LVM. Under /home is /home/misc, where I put /home/misc/movies/ |
| 48 |
/home/misc/music and /home/misc/photos. |
| 49 |
|
| 50 |
This may not be ideal for a production server, but I like it at home, |
| 51 |
because I don't have to screw around with multiple partitions. |
