Mac OS X 10.11.1: mobile time machine creates file on / without any name which is not hidden

Product:OS X Product Version:Mac OS X 10.11.1 (15B42)
Classification:Other Bug Reproducible:Always
 
Summary:
mtm creates a plist without any name whatsoever on / which contains mtmUUID, file is 263 bytes in size and should at least be hidden (and maybe have a name?)

Steps to Reproduce:
disable mtm, delete the file, enable via tmutil enablelocal, boom, file is back

Expected Results:
a plist containing the mtmUUID is fine but it should be hidden on / and the file should have a name

Actual Results:
completely nameless file (ls lists „?“ as name or „“ depending on how you poke it). 263 bytes in size.

Regression:
Happened on previous systems, too, in rare circumstances. Checked HFS, also with -Race, but no errors found. So it doesn’t seem to be HFS

Notes:
Provide additional information, such as references to related problems, workarounds and relevant attachments.

Comments

On my machine, the file is named with a single byte with a value of 1. It can be referenced from bash using $'\x01'.
