Hello there, to work around a few portability issues in a test suite of a Debian package, I need to know which platform (Linux/Hurd/kFreeBSD) I'm currently running on.
This is a shell script, however `dpkg-architecture -qDEB_HOST_ARCH_OS`
isn't quite an option: For obvious reasons I'd like to upstream the
change, and dpkg* isn't available everywhere. The portable approach was
probably examining `uname -s` but appearently on Hurd this returns just
"GNU"[1] - at least on the Hurd porter box exodor -, and that's a bit
vague.
Any suggestions for a sane approach?
As a last resort I might create a very short C program that prints
an identification string based on the constants as listed in
https://sourceforge.net/p/predef/wiki/OperatingSystems/
but this feels like a dirty workaround.

PS: Please Cc me in replies, I'm not subscribed to the hurd list.
[1] As far as I can tell, this string is provided by the kernel via the
uname syscall. On Hurd, I'd change that to something like
"GNU/Hurd" since on kFreeBSD this yields "GNU/kFreeBSD". Take this
as a kernel feature request.
