rcS: changed \+ to * since some busybox builds don't like \+
installer: have busybox symlink itself into /bin
installer: busybox should be setuid'd
installer: install busybox as symlinks
rcS: rearranged mounts, fixed brs request
brs: do not error out on bedrock request, fixed brU -> bru
rcS: try to load fuse
bedrocklinux-installer -> installer

/bedrocklinux-installer will make tab-completing to /bedrock more
difficult than need be.  '/i*' '/R*' and '/L*' are all pretty safe.
