RUMP_WMD(1)             NetBSD 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 some-
     what 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''.
