A query regarding the possibility of dropping support for older kernels in systemd led
to some discussion on the systemd-devel mailing list recently. As might be
guessed, exactly which kernel would be the minimum
supported, what kernel features systemd is using, and when those kernel
features became available, were all part of that conversation.
A component like systemd that is closely tied to the kernel, and the interfaces
different versions
provide, has a number of different factors to consider when making a
decision of this sort.
