.Sh NAME
|
|
.Nm rump_server ,
|
|
.Nm rump_allserver
|
|
.Nd rump kernel server
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl s
|
|
.Op Fl l Ar library
|
|
.Op Fl m Ar module
|
|
.Ar url
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is used to provide a rump kernel service.
|
|
Clients can use the system calls provided by
|
|
.Nm
|
|
via
|
|
.Ar url .
|
|
.Pp
|
|
The difference between
|
|
.Nm
|
|
and
|
|
.Nm rump_allserver
|
|
is that
|
|
.Nm
|
|
offers only a minimalistic set of features,
|
|
while
|
|
.Nm rump_allserver
|
|
provides all rump kernel components which were available when the
|
|
system was built.
|
|
At execution time it is possible to load components from the command
|
|
line as described in the options section.
|
|
.Bl -tag -width indent
|
|
.It Fl l Ar library
|
|
Call
|
|
.Fn dlopen
|
|
on library before initializing the rump kernel.
|
|
In case
|
|
.Ar library
|
|
provides a kernel module, it will appear as a builtin module in the
|
|
rump kernel.
|
|
Any rump component present in
|
|
.Ar library
|
|
will also be initialized.
|
|
.Pp
|
|
The argument
|
|
.Ar library
|
|
can contain a full path or a filename, in which case the standard
|
|
dynamic library search path will be used.
|
|
Libraries are loaded in the order they are given.
|
|
Dependencies are not autoloaded, and the order must be specified
|
|
correctly.
|
|
.It Fl m Ar module
|
|
Load and link a kernel module after the rump kernel is initialized.
|
|
For this to work, the rump kernel must include the vfs faction,
|
|
since the module is loaded using kernel vfs code (see
|
|
.Sx EXAMPLES ) .
|
|
.It Fl s
|
|
Do not detach from the terminal.
|
|
By default,
|
|
.Nm
|
|
detaches from the terminal once the service is running on
|
|
.Ar url .
|
|
.El
|
|
.Pp
|
|
After use,
|
|
.Nm
|
|
can be made to exit using
|
|
.Xr rump.halt 1 .
|
|
.Sh EXAMPLES
|
|
Start a server and load the tmpfs file system module, and halt the
|
|
server immediately afterwards:
|
|
.Bd -literal -offset indent
|
|
$ rump_server -lrumpvfs -m /modules/tmpfs.kmod unix://sock
|
|
$ env RUMP_SERVER=unix://sock rump.halt
