Just as a note, one difference here is that there is support in the archive and package-distribution mechanisms for having multiple versions of a package for different architectures or (I think?) kernels, so that you can build a version with some optional features for one architecture / kernel but a version without those optional features on another - but there is no such support for having multiple versions of a package for different init systems. You can only have one architecture, only one kernel, and only one init system active at any given time. The archive and its infrastructure recognizes this for architectures and (I think) kernels, and supports special handling for them to avoid or work around problems which would (or easily could) otherwise be present. The archive and its infrastructure do not presently recognize this or provide such support for init systems; as such, no such workarounds are available. It seems possible that some of the problems potentially / arguably introduced by having features provided by only a subset of available init systems could be avoided or resolved by having multiple package versions for different init systems, much as we already have for different architectures and in some cases kernels. However, I'm not at all sure that it's clear that the benefit of having such would be worth the trouble of setting it up and maintaining it. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
