# vumount(1)

mount a filesystem or a resource

## NAME

**vumount** – mount a filesystem or a resource

## SYNOPSIS

**vumount** \[*options* ...\] *source* *destination*

## DESCRIPTION

Everything is (or can be seen) as a file. It is part of the philosophy of UNIX. The file hierarchy is the global naming facility.

VUOS follows this principle: VUOS modules use [**mount**(2)](/mount/2.md) not only to mount virtual filesystems but also to activate other virtual services. The mountpoint, *destination* in the synopsis, is the name that will be used to identify the virtual entity/service.

For example, in **vudev** it is possible to mount devices, in **vunet** the mountpoint is the name of the networking stack, [**vustack**(1)](/vustack/1.md) uses the path of the mountpoint to set the current stack for processes.

**vumount** is just a command interface to [**mount**(2)](/mount/2.md). The [**mount**(8)](/mount/8.md) command is a complex tool which includes several features like the management of /etc/fstab and /etc/mtab. [**mount**(8)](/mount/8.md) is a root setuid executable and performs security checks before the actual [**mount**(2)](/mount/2.md) syscall request. [**mount**(8)](/mount/8.md) can be used in VUOS in place of **vumount** but it requires the (virtual) real uid of the executing process to be 0 (root). e.g. [**vusu**(1)](/vusu/1.md) can be used to set the virtual real uid to 0. **vumount** has been designed for VUOS but can be used to run the **mount** system call directly, without all the other management actions provided by [**mount**(8)](/mount/8.md). **vumount** is not setuid root.
