just perusing the simple code in init/noinitramfs.c, which is
what's invoked if you choose not to build in initrd support:
static int __init default_rootfs(void)
{
int err;
err = sys_mkdir("/dev", 0755);
if (err < 0)
goto out;
err = sys_mknod((const char __user *) "/dev/console",
S_IFCHR | S_IRUSR | S_IWUSR,
new_encode_dev(MKDEV(5, 1)));
if (err < 0)
goto out;
err = sys_mkdir("/root", 0700);
if (err < 0)
goto out;
return 0;
...
so, if you choose not to select initrd support, then the above trivial
initial root filesystem better be everything you need to completely
finish the boot process, right? i just want to make sure i'm not
overlooking anything subtle.
