Hi Stefan, ptal. I found that git-crup never runs without error, so it won't
runhooks automatically after crup. This seems to fix it, though there might be a
larger root cause. These were the commands that were run:

+ '[' src = src ']'
+ grep -q -s 'The Chromium Authors' .git/description
+ shift
+ test 4 -ne 0
+ update_toplevel git pull -q origin
+ test pull = pull
/Users/justinlin/Documents/Source/chrome
+ '[' '' = /Users/justinlin/Documents/Source/chrome/src ']'
+ submodule=Users/justinlin/Documents/Source/chrome/src
+ echo '[] updating Users/justinlin/Documents/Source/chrome/src'
[] updating Users/justinlin/Documents/Source/chrome/src
+ git symbolic-ref HEAD
+ git submodule update --quiet Users/justinlin/Documents/Source/chrome/src
+ grep -v '^Skipping submodule'
+ sed 's|^|[/Users/justinlin/Documents/Source/chrome/src] |g'
+ first_args='git pull'
+ shift 2
+ echo '[src] git pull -q' origin
[src] git pull -q origin
+ git pull -q origin
+ sed 's/^/[src] /g'
You need to run this command from the toplevel of the working tree.
+ true
+ status=1
+ '[' 1 -ne 0 ']'
+ echo '[] FAILED to update Users/justinlin/Documents/Source/chrome/src'
[] FAILED to update Users/justinlin/Documents/Source/chrome/src
+ exit 1
[src] Current branch master is up to date.
+ status=0
+ '[' 0 -ne 0 ']'
+ set_target_os
++ git config target.os
