Kakvo znachi "zanulyava", prezapisva sektorite s nuli?

Tova ne e verno,  ponezhe mozhe da ima nyakolko
hard linka kqm fayla i togava rm prosto maha edin ot linkovete.

Ako ima samo edin hard link, *mislya*, che rm pak ne trie samite
sektori na sqdqrzhanieto, a gi markira kato svobodni. Az sqm na
ext3fs i iztrivane na film ot 700MB stava prakticheski momentalno,
s minimalna aktivnost na diska. Ako go prezapisvashe s nuli,
shteshe da e dosta po-dqlgo -- sqdya po tova, kolko otnema da
se napravi cp ili mv na takqv file i kolko shumi diska pri tova.
