Yes this definitely works although it replaces the file and appends
the line to it every time it runs. Is there a cleaner way of doing
it?
tmp/filetest is a file managed by puppet who's contents are two lines
"testme" and "hmm what does this do". The append function appends line
"works" everytime it runs.
[root@ /]$ cat /tmp/filetest
testme
hmm what does this do
works
[root@ /]$ puppetd --test
