Trying to build, the first error I get is

λ ./scripts/patches.sh apply
Stashing Chromium changes..
fatal: pathspec 'carbonyl' did not match any files

Then I don't understand the part which says "When prompted, enter the following arguments:" do you mean when the editor pops open? I tried that but it gave an error when save and quit vi

Is it because its not checked out in the root but its in the path /media/philip/chromium/carbonyl ?
