   3 # this is a DF launcher, replacing the one that ships with DF.
   4 # it's purpose is to launch DF through musl's libc.so, because the DF
   5 # binary has GLIBC's dynlinker hardcoded as interpreter.
   6 # additionally it launches DF through launch-without-heap-randomization.elf.
   7 # it turned out that the way musl's malloc work, DF will crash pretty rapidly
   8 # if heap randomization is enabled (linux default).
   9 # launch-without-heap-randomization.elf will turn that off.
  10 # you can compile it from launch-without-heap-randomization.c:
  11 # gcc launch-without-heap-randomization.c -o launch-without-heap-randomization.elf
