Mount-o REMOUNT,RW/Large use in single-user mode

When our Linux system fails to boot, it is often necessary to go into single-user mode to modify some of the configuration files, or to adjust some parameters. However, after entering the single-user mode, our/file system is read-only mode, can not be modified, then we need to use a command: mount–o remount,rw/This command to make our/path file system into a readable mode, so that the free modification can be achieved.

For example:

Increased the/etc/mtab

/dev/sdb1/install ext3 RW 0 0

/etc/fstab

Label=/install/install ext3 Defaults 1 2

Then the system restarts: it does not come up, prompt

Give root password for maintenance
(or type control-d to continue:)

After entering the root password, you enter the system and want to remove the added content. But the hint is read-only. Do not allow modification

Use the following method

Mount-o remount, RW/

Because root directory/is mounted inread only mode. Type follwing command, then should is able to editrc.sysint script.

Now go and modify the Mtab/fstab file. Last reboot, the system started successfully
