The proposal not seem to be a significant performance enhancer. Fairly stock Fedora 18, on SSD: [root@f18v ~]# systemd-analyze Startup finished in 2185ms (kernel) + 1493ms (initrd) + 5834ms (userspace) = 9513ms After making 91-host-only.conf and running dracut -f. I get a 7.2MB initramfs instead of 31MB. And: [root@f18v ~]# systemd-analyze Startup finished in 1892ms (kernel) + 769ms (initrd) + 6086ms (userspace) = 8749ms -------Same test, different CPU, HDD: Stock: [root@f18s boot]# systemd-analyze Startup finished in 1180ms (kernel) + 3538ms (initramfs) + 20934ms (userspace) = 25653ms host-only initramfs: [root@f18s ~]# systemd-analyze Startup finished in 1082ms (kernel) + 2914ms (initramfs) + 25410ms (userspace) = 29407ms Curiously, the userspace figure consistently is longer when the initramfs is smaller. (Now if someone wants to explain how the kernel has 1/2 the time on a core2duo+HDD, compared to corei7+SSD, I can accept that offline.)
