Missing /etc directory in docs on how to create the rootfs

[thass0]

The README states:

In this example, the populated root filesystem will look like this:

rootfs/
├── lib
│   └── x86_64-linux-gnu
│       └── libc.so.6
├── lib64
│   └── ld-linux-x86-64.so.2
└── helloworld

Following the rest of the steps in the README results in this crash when running the helloworld example for the first two times:

[    0.102110] ERR:  [appelfloader] <conffile.c @   92> /etc/resolv.conf: Failed to create: Permission denied (13)
[    0.104548] ERR:  [libukboot] <boot.c @  427> Init function at 0x11d420 returned error -13
[    0.106414] CRIT: [libuk9p] <9pdev.c @  118> Assertion failure: uk_list_empty(&fid_mgmt->fid_active_list)

After the two run, the rootfs has changed (the first run seems to create the resolv.conf file, the second the hosts file; both are empty):

ls rootfs/etc
.  ..  hosts  resolv.conf 

If the etc directory and the two files are present, it works from the start. Not sure if this is a Unikraft bug or an issue with the docs here.
