Partition Types

Partition types are defined in sys/sys/gpt.h

These MidnightBSD types have been used for some time, and predate 1.0.

For MBR partitions, we piggyback off FreeBSD types. With GPT, we have the following types:

#define GPT_ENT_TYPE_MIDNIGHTBSD \ {0x85d5e45a,0x237c,0x11e1,0xb4,0xb3,{0xe8,0x9a,0x8f,0x7f,0xc3,0xa7}} #define GPT_ENT_TYPE_MIDNIGHTBSD_NANDFS \ {0x85d5e45e,0x237c,0x11e1,0xbd,0x04,{0x00,0xe0,0x81,0x28,0x6a,0xcf}} #define GPT_ENT_TYPE_MIDNIGHTBSD_SWAP \ {0x85d5e45b,0x237c,0x11e1,0xb4,0xb3,{0xe8,0x9a,0x8f,0x7f,0xc3,0xa7}} #define GPT_ENT_TYPE_MIDNIGHTBSD_VINUM \ {0x85d5e45c,0x237c,0x11e1,0xb4,0xb3,{0xe8,0x9a,0x8f,0x7f,0xc3,0xa7}} #define GPT_ENT_TYPE_MIDNIGHTBSD_ZFS \ {0x85d5e45d,0x237c,0x11e1,0xb4,0xb3,{0xe8,0x9a,0x8f,0x7f,0xc3,0xa7}} #define GPT_ENT_TYPE_MIDNIGHTBSD_BOOT \ {0x85d5e45e,0x237c,0x11e1,0xb4,0xb3,{0xe8,0x9a,0x8f,0x7f,0xc3,0xa7}} #define GPT_ENT_TYPE_MIDNIGHTBSD_UFS \ {0x0394ef8b,0x237e,0x11e1,0xb4,0xb3,{0xe8,0x9a,0x8f,0x7f,0xc3,0xa7}}

These get defined in GEOM like so: /usr/src/sys/geom/part/g_part_gpt.c:static struct uuid gpt_uuid_midnightbsd = GPT_ENT_TYPE_MIDNIGHTBSD; /usr/src/sys/geom/part/g_part_gpt.c:static struct uuid gpt_uuid_midnightbsd_boot = GPT_ENT_TYPE_MIDNIGHTBSD_BOOT; /usr/src/sys/geom/part/g_part_gpt.c:static struct uuid gpt_uuid_midnightbsd_nandfs = GPT_ENT_TYPE_MIDNIGHTBSD_NANDFS; /usr/src/sys/geom/part/g_part_gpt.c:static struct uuid gpt_uuid_midnightbsd_swap = GPT_ENT_TYPE_MIDNIGHTBSD_SWAP; /usr/src/sys/geom/part/g_part_gpt.c:static struct uuid gpt_uuid_midnightbsd_ufs = GPT_ENT_TYPE_MIDNIGHTBSD_UFS; /usr/src/sys/geom/part/g_part_gpt.c:static struct uuid gpt_uuid_midnightbsd_vinum = GPT_ENT_TYPE_MIDNIGHTBSD_VINUM; /usr/src/sys/geom/part/g_part_gpt.c:static struct uuid gpt_uuid_midnightbsd_zfs = GPT_ENT_TYPE_MIDNIGHTBSD_ZFS;

The friendly names for these as displayed by tools: /usr/src/sys/geom/part/g_part.c: { "mnbsd-boot", G_PART_ALIAS_MIDNIGHTBSD_BOOT }, /usr/src/sys/geom/part/g_part.c: { "mnbsd-nandfs", G_PART_ALIAS_MIDNIGHTBSD_NANDFS }, /usr/src/sys/geom/part/g_part.c: { "mnbsd-swap", G_PART_ALIAS_MIDNIGHTBSD_SWAP }, /usr/src/sys/geom/part/g_part.c: { "mnbsd-ufs", G_PART_ALIAS_MIDNIGHTBSD_UFS }, /usr/src/sys/geom/part/g_part.c: { "mnbsd-vinum", G_PART_ALIAS_MIDNIGHTBSD_VINUM }, /usr/src/sys/geom/part/g_part.c: { "mnbsd-zfs", G_PART_ALIAS_MIDNIGHTBSD_ZFS },
