I'm pretty sure that the file copying subsystem always uses checksums
regardless of what you ask.  This is a bug.  I thought I'd developed
it to support any of them, but realized recently I had not.

Checksumming with md5-files doesn’t seem the only problem here, the checksum-type “mtime” seems to have a “bug”:

On every sync, the mtime of the target file gets changed, if puppet compares the source-file (mtime some years ago) with the target-file (some 5 minutes ago), it has to resync that file. mtime only seems to make sense, if the corresponding time gets set by puppet after the sync, otherwise we shouldn’t support mtime as checksum-type, I guess.

Another problem derived from this bugreport is the one luke mentioned as “pretty shure it is a bug”. In source:/trunk/lib/puppet/type/pfile/checksum.rb@1760#L240 the corresponding checksum-type should be used, I guess, not a default. But for now I’m to tired to create a patch, or debug any futher, sorry :)

here is my “testcase”, with which I debugged the problem:

$ cat site.pp
file { "/home/thorsten/copy": 
        source => "/home/thorsten/huge",
        checksum => "mtime"
}

Nearly positive this works correctly now, or at least will in rowlf.
