If the new config file is in the autoloaded file list in the lens, then
just by setting the node in Augeas, it'll create the file.  For example:

$ ls etc/securetty
ls: cannot access etc/securetty: No such file or directory
$ augtool -r . -s set /files/etc/securetty/01 tty1
Saved 1 file(s)
$ cat etc/securetty
tty1

You can change the /augeas tree to load files with a particular lens:

Raphael has a useful "augload" utility that sets this up too:
