RUMP_WMD(1) General Commands Manual RUMP_WMD(1)
NAME
rump_wmd - Resolve rump kernel component dependencies
SYNOPSIS
rump_wmd [-hv] [-L dir] -lcomponent ...
DESCRIPTION
The rump_wmd 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 rump_wmd is accepted as
command line input by rump_server(1).
The command line options are:
-h Print the usage.
-L dir By default, rump kernel components in /usr/lib are examined.
If this option is supplied, components in dir are examined
instead.
-v Increase debug output from the utility. This option may be
given multiple times.
The desired components are given using -lcomponent. This parameter may
be specified multiple time and must be the last set of parameters.
EXAMPLES
Resolve dependencies for FFS:
$ rump_wmd -lrumpfs_ffs
DEBUG0: Searching component combinations. This may take a while ...
DEBUG0: Found a set
-lrumpdev -lrumpdev_disk -lrumpvfs -lrumpfs_ffs
Resolve dependencies for NFS, use IPv6 networking and the virtif network
interface:
$ 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

CAVEATS
Since rump_wmd 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.
FUN FACTS
rump_wmd is short for "rump, where's my dependency".
