18 The userland tools either work or they don't. Nothing stops working as
19 soon as an update becomes available. The versions of the tools in the
20 root filesystem don't matter at this point, because the root filesystem
21 is not mounted. The initramfs is a standalone environment that doesn't
22 stop working just because someone changed a file on an unmounted
23 filesystem.
