RUMP_WMD(1) General Commands Manual RUMP_WMD(1) NAME rump_wmd - Resolve rump kernel component dependencies SYNOPSIS rump_wmd [-hv] [-L dir] -l component 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 -l component. 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 SEE ALSO rump_server(1) 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". NetBSD 8.99.34 January 28, 2014 NetBSD 8.99.34
