fatal: /: '/' is outside repository at '/mnt/code/firefox'
Error running mach:

    ['try', 'fuzzy', '-q', "'-qr !talos !raptor", '-q', '^webrender-']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

CalledProcessError: Command '(u'/usr/bin/git', u'add', '/', 'm', 'n', 't', '/', 'c', 'o', 'd', 'e', '/', 'f', 'i', 'r', 'e', 'f', 'o', 'x', '/', 't', 'r', 'y', '_', 't', 'a', 's', 'k', '_', 'c', 'o', 'n', 'f', 'i', 'g', '.', 'j', 's', 'o', 'n')' returned non-zero exit status 128

This wasn't happening yesterday, I just grabbed the latest central and it happened.

Looks like a dupe of bug 1630668 to me. Try rebasing on autoland.
