If you're exceptionally paranoid, there are 3 ways of making metadata
writes synchronous on ext2:
-per-file if you have the program source: use the O_SYNC flag to open()
-per-file if you don't have the source: use "chattr +S" on the file
-per-filesystem: add the "sync" option to mount (or in /etc/fstab)
