looks like the CI build failed in a bunch of places that are unrelated to my change, and it was also failing to build before my change. what do you need from me to look at this? |

+1 I don't use busybox, but we do this same exact fix for a symlinking problem at my company. |

sounds like, this makes sense - maybe even to get into 9.1.14.0 |

I'll merge this to 9.1.14 and master. Thanks for the help @zendes! |

I ran into some issues with using JRuby on a system that uses busybox as it's userland, and without this patch things won't work.
For a bit of background: busybox's goal is to be a tiny userland (commands like ls and mv) for space-constrained devices. One of the ways it does this is by being a multi-call binary. You symlink it with names such as ls and cp, and it uses $0 to determine how it's called and thus what it should do. JRuby resolves the symlink before it execs, so busybox loses $0 and thus doesn't know what the user originally called. This patch fixes that.
