Depends of course on the type of FS used but basically this could be summed up by: Linux will preserve the information of the existence of the newly created file with the same accuracy as the content of the file itself. Solaris (and historically most BSD derived FSes) will force the information that that file was created on disk even if the content of the file itself isn't yet preserved. Solaris will force the synchronization of the metadata, while linux will handle FS metadata as normal data and not put specific constraints on the metadata flush. At least that's my understanding based on 7-8 years old outdated now informations on the Solaris side, so take it with a huge cube of salt :-) Now on Linux, you are likely to be using ext3 based filesystem where all data on disk will anyway been guaranteed to be in a coherent state (or a coherent state can be reconstructed very quickly when remounting the filesystem in case of a crash). The only difference is how timely that coherent state is flushed on disk.
