.SH NAME
 | 
						|
vbfs \- VirtualBox Shared Folder File System server
 | 
						|
.SH SYNOPSIS
 | 
						|
\fBmount \-t vbfs \fR[\fB\-r\fR] \fB\-o
 | 
						|
\fBshare=\fIsharename\fR[\fB,\fIoptions\fR] \fBnone \fImountpoint
 | 
						|
.SH DESCRIPTION
 | 
						|
The \fBvbfs\fR server allows one to mount a VirtualBox shared folder as a file
 | 
						|
system. This makes it possible to access selected portions of the VirtualBox
 | 
						|
host file system when MINIX is run as a VirtualBox guest.
 | 
						|
.PP
 | 
						|
The above mount command will mount the vbfs file system onto the directory
 | 
						|
\fImountpoint\fR. The \fB\-r\fR mount option makes the file system read-only;
 | 
						|
note that shared folders may independently have been configured as read-only
 | 
						|
on the VMware host. The \fIoptions\fR field is a string consisting of
 | 
						|
comma-delimited \fIkey\fR or \fIkey\fB=\fIvalue\fR options.
 | 
						|
The vbfs server can mount only one shared folder at a time, and therefore,
 | 
						|
specifying a \fBshare\fR name is required.
 | 
						|
The other options are optional. The following options are supported.
 | 
						|
.TP 4
 | 
						|
\fBshare=\fIname\fR
 | 
						|
This required option specifies the share name to mount. It is currently not
 | 
						|
possible to list the available share names from within MINIX3.
 | 
						|
.TP
 | 
						|
\fBprefix=\fIpath\fR
 | 
						|
This option sets a path prefix that will be prepended to all file system
 | 
						|
operations on the host system. The default is the empty path, exposing the
 | 
						|
entire share. Leading and trailing slashes are ignored.
 | 
						|
.TP
 | 
						|
\fBuid=\fInumber\fR
 | 
						|
This sets the user ID used for all the files and directories in the file
 | 
						|
system, allowing a non-root user to be the owner. The value must be specified
 | 
						|
as a decimal number.
 | 
						|
The default is root (the number \fB0\fR).
 | 
						|
.TP
 | 
						|
\fBgid=\fInumber\fR
 | 
						|
Likewise, sets the group ID for all files and directories.
 | 
						|
The default is operator (the number \fB0\fR).
 | 
						|
.TP
 | 
						|
\fBfmask=\fInumber\fR
 | 
						|
This option sets the file permission mask of regular files. It is specified as
 | 
						|
an octal number. For example, a value of \fB600\fR makes all files readable and
 | 
						|
writable by the owning user (see the "\fBuid\fR" option).
 | 
						|
The default is \fB755\fR.
 | 
						|
.TP
 | 
						|
\fBdmask=\fInumber\fR
 | 
						|
Likewise, sets the file permission mask of directories.
 | 
						|
The default is also \fB755\fR.
 | 
						|
.SH EXAMPLES
 | 
						|
.TP 20
 | 
						|
.B mount \-t vbfs -o share=myshare none /usr/myshare
 | 
						|
# Mount the "\fImyshare\fR" shared folder on \fI/usr/myshare\fR
 | 
						|
.TP 20
 | 
						|
.B mount \-t vbfs \-o share=shared,prefix=foo/bar,uid=20,fmask=644 none /mnt
 | 
						|
# Mount the "\fIfoo/bar\fR" subtree from the "\fIshared\fR" shared folder on
 | 
						|
\fI/mnt\fR
 | 
						|
.SH LIMITATIONS
 | 
						|
VBFS has been designed to provide a convenient means to exchange files between
 | 
						|
the guest and the host system, not as a complete file system implementation.
 | 
						|
As such, it comes with many limitations. Some of these are VBFS implementation
 | 
						|
shortcomings; some are the result of behavioral differences between the host
 | 
						|
file system and the guest's expectations; some are the result of a mismatch
 | 
						|
between MINIX's VFS/FS protocol and the requirements from VBFS; and finally,
 | 
						|
some are the result of the user's ability to change the file system on the
 | 
						|
host system at any time.
