This occurred when I tried to map a folder using destination name that same as the program name:

{
  "MapDirs": {
    "/home/arknable/Development/Project/nanovms/example/hello/*": "/hello"
  }
}

and the program name is hello:

arknable@arknable-x1c:~/.../hello$ ls -l
total 40608
-rw-rw-r-- 1 arknable arknable      159 Jun 18 18:19 config.json
-rwxrwxr-x 1 arknable arknable 41573332 Mei 10 03:08 hello
-rw-rw-r-- 1 arknable arknable      239 Mei 29 17:55 hello.js

Probably better to output a human-readable message instead of panic ?
