The standard doesn't really command the behaviour, as it seems, but we
might want to look again after SUS v3 has been released (supposed to
happen later this year) - the SUS compliance was rather on fsync than on
rename/link.

However, I'd rather not choose the default for somebody else, because he
may have different requirements, a compile-time switch to set the
default should be fine, THIS one might indeed default to dirsync/noasync
unless changed by make {x,menu,}config.

Assuming that the chattr +S is accompanied by a corresponding -o sync
mount option, I'd expect that the dirsync option be available as chattr
option and as mount option, and choosing default mount options should be
rather easy.
