Indeed, you have a skeleton for each init option. Of course, all the selects there would have to look like select BR2_PACKAGE_SKELETON_SYSV if BR2_ROOTFS_SKELETON_DEFAULT I'm not entirely sure if it's an improvement, but I have the feeling it's easier to follow if the different skeleton options are put together with the different init options.

I also tried that, but I found it uglier, because it is split away in various options, while here it is fully concentrated in a single one, so it is (arguably) easier to maintain... Regards, Yann E.

Currently, we use the same skeleton for sysv-like init systems and systemd, even though systemd has some peculiarities that makes out default skeleton unfit. So, we'll need to provide different skeletons (really, only part of it) for sysv-like and systemd. Introduce two new skeleton packages, aptly named skeleton-sysv and skeleton-systemd, one for each, that are both providers of the skeleton package, in lieue of the skeleton-common, which is now a simple dependency of both the two new skeletons. Those packages are empty for now. In followup changes: - sysv-specific stuff will be moved out of skeleton-common and into skeleton-sysv; - systemd-specific stuff will be added to skeleton-systemd.
