We started to roll out systemd today.
But don’t panic! Your system will still boot with openrc and everything is expected to be working without troubles.
We are aiming to support both init systems, at least for some time (long time I believe) and having systemd replacing udev (note: systemd is a superset of udev) is a good way to make systemd users happy in Sabayon land. From my testing, the slowest part of the boot is now the genkernel initramfs, in particular the modules autoload code which, as you may expect, I’m going to try to improve.
Please note that we are not willing to accept systemd bugs yet, because we’re still fixing up service units and adding the missing ones, the live media scripts haven’t been migrated and the installer is not systemd aware. So, please be patient ;-)
Having said this, if you are brave enough to test systemd out, you’re lucky and in Sabayon, it’s just 2 commands away, thanks to eselect-sysvinit and eselect-settingsd. And since I expect those brave people to know how to use eselect, I won’t waste more time on them now.
