--- Comment #4 from Theodore Tso (tytso@mit.edu) ---
As Lukas said, "truncate" is not the only way to create sparse files.  And
there are many Unix / Linux programs that depend on the ability to create
sparse files, since Unix support of sparse files goes back at roughly 50 years
(half a century).

The fact that clueless users / sysadmins might not understand basic Unix/Linux
behavior is not a bug in Linux.   There are plenty of other ways that an
experienced sysadmin might shoot themselves in the foot....
