Ubuntu boot automatically mount partition

First, look at the system's disk code:

Fdisk-l

disk/dev/sda:120.0 GB, 120034123776 bytes

255 heads, Sectors/track, 14593 cylinders, total 234441648 sectors

Units = Sector of 1 * A-bytes

Sector size (logical/physical): bytes/512 bytes

I/O size (minimum/optimal): bytes/512 bytes

Disk IDENTIFIER:0X000214D1

Device Start point end block Id system

disk/dev/sdb:500.1 GB, 500107862016 bytes

255 heads, Sectors/track, 60801 cylinders, total 976773168 sectors

disk/dev/sdc:8178 MB, 8178892800 bytes

Disk Identifier:0x16c0ca45

Device Start point end block Id system

/DEV/SDC1 * 1552 15974399 7986424 b W95 FAT32

Note: The root directory/must be mounted prior to other directories.

The other mount point must be a directory that has already been created.

Use the following command to view the UUID for another disk:

sudo blkid

The results are as follows:/dev/sda1:uuid= "70FB376C-17C2-4CE1-A263-727F647949CF" type= "Ext4"

/dev/sda5:uuid= "0c5f073a-ad3f-414f-85c2-4af83f6a437f" type= "swap"

/dev/sdb1:uuid= "11263962-9715-473f-9421-0b604e895aaa" type= "Ext4"

/dev/sdb2:uuid= "88928fea-5dd3-47b1-9931-bb107d74371e" type= "Ext4"

Next, modify the automatically mounted configuration file: sudo vim/etc/fstab

Modified as follows: UUID=70FB376C-17C2-4CE1-A263-727F647949CF/EXT4 Errors=remount-ro 0 1

# Swap was on/dev/sda5 during installation

uuid=0c5f073a-ad3f-414f-85c2-4af83f6a437f None swap SW 0 0

Uuid=11263962-9715-473f-9421-0b604e895aaa/data EXT4 Defaults 0 1

Uuid=88928fea-5dd3-47b1-9931-bb107d74371e/export EXT4 Defaults 0 1

The last two actions add a mount point.

Note that you should never set the Mount directory to/, or if the original root directory will be overwritten, the system will be dead.
