Comment 2 for bug 1486113

To be fair, this isn't completely useless.
If we simply moved the writing of files to after users were created, then less of the boot could be affected by your written files.

As a (possibly contrived) example, as it is right now you can use write_files to replace 'adduser' and then cloud-init would call the replaced version of adduser when adding users. If write_files happened later you could not do that.

I would like to get this to work though.
2 options:
a.) add 'write_files_late' that runs after users are created (or write_files_early and write_files) basically 2 different points in boot.
b.) magically determine if 'owner' isn't around that we should re-try this after the usergroups are created.
c.) extend format of write_files to include 'early' or 'late' that would indicate to cloud-init explicitly that it should happen after users or before users creation.
