reading init/noinitramfs.c, which is what is compiled into the
kernel, this is what happens if you choose no initrd/initramfs support
whatsoever:
=====
/*
* Create a simple rootfs that is similar to the default initramfs
*/
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;
out:
printk(KERN_WARNING "Failed to create a rootfs\n");
return err;
}
=====
fair enough, but what is it that is currently mounted(?) that these
files/directories are being created in? is this an initial tmpfs, or
what? is there a line somewhere in init/main.c that corresponds to
where this initial mount point comes from? thanks.
