fstab

The abbreviation stands for fstab file system table. This is a file / etc / fstab or / etc / vfstab file that contains a list of all to mount the file systems in Unix-like operating systems. The usable options often differ depending on the operating system platform, file system, and age. Detailed information on the respective system is obtained by typing

The order of entries (rows ) and the number of spaces in a row is basically irrelevant. Some operating systems use automatic entries within the file and format it there. This is particularly the case with the large RPM-based Linux distributions. The mechanisms by which this is determined, whether it is an automatic entry (which can be removed and must) or a manual, thus differ from striking. In particular, some distributions is therefore at all to warn against manual changes to the fstab / vfstab to make.

The loss of such file or the damage leads in most cases to a not bootable system. But this is easy to fix usually through a live CD.

The name of the file depends on the operating system, / etc / vfstab is in Solaris / BSD environment in use, on AIX, the file is called / etc / filesystems.
