Does it make sense to move some of these down to ash/system/chromeos ?

[James Cook, 2016/09/20 18:14:42]

I prefer to keep them here. Note that there are both //ash/system/chromeos and
//ash/common/system/chromeos directories (for classic ash vs. mustash code). The
former probably won't go away entirely until we turn off classic ash.

Also, usage isn't that concentrated in the system directories:

git grep "include \"chromeos" ash

I think it's easier to reason about the deps if they all live here.

OK
