Some general thoughts. 1. speed at initramfs creation time is not sooo important. Normally this is only done once in a while and not every day. Boot speed is more important. 2. if you care about speed of creation and size of the initramfs, turn on "hostonly" in /etc/dracut.conf > Yes, I'm going to work on it. > That's cool! I accept patches :-) -- To unsubscribe from this list: send the line "unsubscribe initramfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
