There are only two files with crack string in file name, https://code.google.com/p/chromium/codesearch#search/&q=lang:%5Ec%2B%2B$%20file:crack*&sq=package:chromium&type=cs.  To me, they're real crack thing.

Even crhomium use Crack word some where, not the good reason you use that word. Crack is very wide meaning word, in your case  you're offering the mount point thing, so please be more specific when naming class/function/variable.
