Not true. There *is* a problem at the software level - on Linux, current BSD (and apparently also on QNX) you must fsync the containing directory when you make changes to the contents of a directory (create/delete/rename files). This is above and beyond whatever lies the hardware layer may tell you. It's a documented requirement in Linux, at least. It is also independent of whether or not the filesystem uses journaling. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
