rumpuser -- rump user namespace helper routines
rump User Library (librumpuser, -lrumpuser)
rumpuser is a user namespace helper library for runnable userspace meta
programs. From rump emulation code compiled with -D_KERNEL is it not
possible to directly call routines such as system calls for reading and
writing files or devices. This is where rumpuser comes into play by pro-
viding a bridge between the two namespaces. Another example of its ser-
vices is a way to call pthread routines, used for emulating kernel
threads and synchronization mechanisms in rump.
