Time > is not needed for initramfs. Are I2C drivers "critical stuff"? What about AHCI drivers? What about all the USB HCI drivers? USB Storage can certainly be loaded from an initramfs, yet it's =y. LED triggers? Loads of RTC drivers that are marked as =y? XOR drivers? VIRTIO drivers? Filesystems? I seem to remember Red Hat sets even popular filesystems to be a module in their kernel. Clearly, "defconfig=y is only for critical stuff" is rather false in practice, and I suspect is little more than a desire rather than a rule. I suspect it's more "defconfig=y is for stuff that makes most platforms successfully boot without an initramfs". -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
