|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility can be used to resolve the link dependencies of rump kernel
|
|
components.
|
|
This functionality is useful when desiring to run a rump kernel with
|
|
a given set of drivers, but not being sure what the dependencies of
|
|
those drivers are.
|
|
The output of
|
|
.Nm
|
|
is accepted as command line input by
|
|
.Xr rump_server 1 .
|
|
.Pp
|
|
The command line options are:
|
|
.Bl -tag -width Fl
|
|
.It Fl h
|
|
Print the usage.
|
|
.It Fl L Ar dir
|
|
By default, rump kernel components in
|
|
.Pa /usr/lib
|
|
are examined.
|
|
If this option is supplied, components in
|
|
.Ar dir
|
|
are examined instead.
|
|
.It Fl v
|
|
Increase debug output from the utility.
|
|
This option may be given multiple times.
|
|
.El
|
|
.Pp
|
|
The desired components are given using
|
|
.Fl l Ns Ar component .
|
|
This parameter may be specified multiple time and must be the last
|
|
set of parameters.
|
|
.Sh EXAMPLES
|
|
Resolve dependencies for FFS:
|
|
.Bd -literal -offset indent
|
|
$ rump_wmd -lrumpfs_ffs
|
|
DEBUG0: Searching component combinations. This may take a while ...
|
|
DEBUG0: Found a set
|
|
-lrumpdev -lrumpdev_disk -lrumpvfs -lrumpfs_ffs
|
|
.Ed
|
|
.Pp
|
|
Resolve dependencies for NFS, use IPv6 networking and the virtif
|
|
network interface:
|
|
.Bd -literal -offset indent
|
|
$ rump_wmd -lrumpfs_nfs -lrumpnet_netinet6 -lrumpnet_virtif
|
|
DEBUG0: Searching component combinations. This may take a while ...
|
|
DEBUG0: Found a set
|
|
-lrumpnet -lrumpnet_net -lrumpvfs -lrumpfs_nfs -lrumpnet_netinet6 -lrumpnet_virtif

|
.Sh CAVEATS
|
|
Since
|
|
.Nm
|
|
uses trial-and-error brute force resolution, it runs somewhat slow.
|
|
If several seconds are spent for dependency resolution, the benefit of
|
|
a rump kernel booting in 10ms is somewhat lost.
|
|
Caching the output is highly recommended.
|
|
.Sh FUN FACTS
|
|
.Nm
|
|
is short for
|
|
.Dq rump, where's my dependency .
