When I created my new Ember project, the new directory had 65_980 files in it. Sixty five thousand, nine hundred and eighty files!
After the earlier projects, this was quite a shock and I wondered if I’d done something wrong. I suggest warning people what to expect.
And on my Linux system, this is too many files for atom and ember server to be able to co-exist. Whichever started second would report it was exceeding the number of file system watchers allowed. (Still worked fine as editor or server respectively, but couldn’t auto-detect changes.)
