The BIOS boot partition is there to enable a non-EFI system to boot from |
16 |
a GPT partitioned disk, it is not the same as /boot. If you want a |
17 |
separate /boot, it is not a requirement, you need to create is as a |
18 |
separate partition, like this |
19 |
|
20 |
% sudo fdisk -l /dev/sda |
21 |
|
22 |
Disk /dev/sda: 2.7 TiB, 3000592982016 bytes, 5860533168 sectors |
23 |
Units: sectors of 1 * 512 = 512 bytes |
24 |
Sector size (logical/physical): 512 bytes / 4096 bytes |
25 |
I/O size (minimum/optimal): 4096 bytes / 4096 bytes |
26 |
Disklabel type: gpt |
27 |
Disk identifier: 04EFD165-FDDF-4C24-BA81-868B97BF9949 |

/dev/sda1 2048 4095 1M BIOS boot partition |
31 |
/dev/sda2 4096 2101247 1G Linux filesystem |
32 |
/dev/sda3 2101248 35655679 16G Linux swap |
33 |
/dev/sda4 35655680 5860533134 2.7T Linux filesystem |

|

Here sda1 is the BIOS boot and sda2 is /boot. |

If you are using GPT partitons, and you should, gdisk is the tool to use |
42 |
(emerge sys-apps/gptfdisk). |

GPT is not hindered by any of that legacy "4 partitions is enough for |
48 |
anyone so lets kludge in some more" crap, you just create partitions. |
