Unix Tip: Remounting root

By Sandra Henry-Stocker

During the booting of Solaris, both the / and /usr file systems are mounted read-only and then later, before the boot process is fully complete, remounted read-write. This is all part of the normal boot process and no reason for concern. Disruptions to the normal boot sequence, however, can leave you with a file system that is mounted read-only and requiring repair with no obvious way to fix the problem. Do situations such as this require you to boot from CD, DVD or from a boot server before you can edit the files or scripts that are sabotaging your boot process? No, you can make use of the mount command's handy remount option and save yourself a lot of time and trouble.

Let's say that you are booting a system and you run into these errors.
