Yup, assuming the kernel-to-init code understands chained symlinks it
would be relatively easy to port all init systems to the
"alternatives" feature :
The generic name is not a direct symbolic link to the selected
alternative. Instead, it is a symbolic link to a name
in the alternatives directory, which in turn is a symbolic link to
the actual file referenced.
