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) 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) uses the path of the mountpoint to set the current stack for processes.

       vumount  is  just a command interface to mount(2).  The mount(8) command is a complex tool which includes
       several features like the management of /etc/fstab and /etc/mtab.  mount(8) is a root  setuid  executable
       and performs security checks before the actual mount(2) syscall request.  mount(8) 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) 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).  vumount is not setuid root.
