Is `-no-fsync' the only difference?  How much more secure does this
make star over tar?  My guestimation tells me that there's only really
a difference in case of a system crash during/right after tarball
extraction.

If you *need* to have the fsync in place because of an unstable
system, you've got quite more servere problems to care about...
