I haven't tried that patch with recent versions of systemd, though. Unless systemd has started using even more signals or introduced even more gaps for no reason at all. > Additionally, given the fact that we have very little users and live > in debian/gentoo unstable That's Debian unstable and Gentoo /stable/ thank you very much. :) > would IMHO justify such an incompatible change. Gentoo dropped support for GNOME and KDE years ago (except for some of the base libraries such as glib and gtk+ of course). The point being that these fat window managers run utterly slow (exactly as they do on much more recent x86 hardware). Interest in supporting systemd therefore never went beyond the purely academic interest displayed in [1]. Luckily, Gentoo already uses an alternative, modern init system. Gentoo/HPPA has little need for systemd, I would guess. > The other option would be to increase NSIG in kernel from 64 to 128 > or higher.

Gentoo has no need for systemd so all these changes would mean upgrading kernel and libc requires a lot more attention, and systemd could equally well compact the ill-chosen RT signal range.
