Hi,
Because people seem to think this is some obscure corner case, I thought
I'd write up a very simple test case to trigger the problem:
First, some setup:
crb@chris ~ $ echo testing > testfile
crb@chris ~ $ ln -s testfile testlink
First test, to create a file that doesn't exist:
crb@chris ~ $ puppet resource file $(pwd)/newfile ensure=file
links=follow source=$(pwd)/testlink mode=0644
err: /File[/home/crb/newfile]/ensure: change from absent to present
failed: Could not rename temporary file /home/crb/newfile.puppettmp_6080
to /home/crb/newfile: File written to disk did not match checksum;
discarding changes ( vs {md5}d41d8cd98f00b204e9800998ecf8427e)
file { '/home/crb/newfile':
ensure => 'absent',
}
As you can see, the file is not created and Puppet produces an error.
Second test, to update the contents of the file if it exists with the
wrong content:
crb@chris ~ $ echo foobar > newfile
crb@chris ~ $ puppet resource file $(pwd)/newfile ensure=file
links=follow source=$(pwd)/testlink mode=0644
file { '/home/crb/newfile':
ensure => 'file',
group => '1000',
mode => '644',
}
crb@chris ~ $ cat newfile
foobar
This time, Puppet does not produce an error at all, but the contents of
the file remains unchanged and un-managed. In this case, this is silent
corruption as Puppet fails to enforce the content change on the file.
Best regards,
Chris
