Once again #KDE tries to get rid of minority distributions. This time by replacing SDDM with PLM (plasma login manager). PLM depends on systemd.
So sooner or later no KDE for #alpineLinux, #FreeBSD, #Gentoo, #NetBSD, #OpenBSD, #Slackware, #VoidLinux, etc.

For #BLFS it is no problem as BLFS itself recently discontinued its non-systemd version.
#LFS

@txt_file OpenBSD never had a port of SDDM to begin with, KDE Plasma can be started with any display manager, the pkg-readme has an example for starting it from .xsession.

OpenBSD Ports Readme: port meta/kde,-plasma

@brynet yes but I expect other KDE parts will soon get the same dependency.
