Not sure I like this solution; it pulls in a bunch of code from syscall to get the cwd at process init. |

Hmm, I'm not sure I like this name. What about storeExecutablePath or something like that?

Why use 1024 and then use 4 times that size in the actual buffer? (Also, it would help to give a pointer to why that is the right value, like a link to a man page or something).

You could consider using unsafe.String here to avoid an allocation. It should be safe, since buf is never modified afterwards. (The potential downside is that executablePath will then always be 4kB in size - not sure whether that's a good tradeoff).
