New issue 874 by [email protected]: Add fsync call to atomicUpdateFile
http://code.google.com/p/ganeti/issues/detail?id=874
Currently it can happen that if the master node crashes in the process of
renaming an atomically created file, the content of the file won't get
flushed, but the directory entry link will, losing the content of the file.
Therefore it's necessary to add a 'fsync' call before renaming the
temporary file to the original name.
While including 'fsync' into 'unix' has been discussed recently,
http://www.haskell.org/pipermail/libraries/2013-December/thread.html#21756
it doesn't seem it got accepted, so we'll have to add the system call
ourselves.
