Recently both Debian and Ubuntu decided to make the switch to Systemd. With more and more distros switching to Systemd, will OpenBSD do the same?
Systemd's license is incompatible with OpenBSD, thus it would need to be rewritten from scratch (and it would probably refactored too). For systemd to appear in OpenBSD there needs to be a benefit to OpenBSD... not simply convenience for people moving from Linux. This is how pf was born: IPFilter was removed from OpenBSD due to concerns about its license and the pf developers refactored IPFilter's baroque rules syntax for simplicity and consistency.
