NAME
rumpfs —
rump kernel root file
system
LIBRARY
rump kernel (librumpvfs, -lrumpvfs)
DESCRIPTION
rumpfs is a simple in-memory file system for rump kernels. It
is automatically mounted as the root file system of a rump kernel at boot
time, provided that the VFS faction is configured into the rump kernel
instance.
The three main features of
rumpfs are:
- providing a hook for accessing host files via the
rump_etfs(3)
interfaces.
- supporting enough of file and directory interfaces to
facilitate simple operations such as hosting config files or creating
mount points.
- being small and lightweight so as to keep a barebones rump
kernel lightweight.
rumpfs is not intended for hosting large files or big
directory hierarchies. If faced with such a use case, mounting a tmpfs file
system inside the rump kernel is recommended.
