removing an ext2fs file forces disk activity

[Marcus Brinkmann]

Hi,

I just found out that

while touch /tmp/foo; do rm /tmp/foo; done

causes a lot of disk activity.  Further tests showed that the disk is
activated for each rm.  Is this a hard requirement?  In Linux, the loop
above does not cause any disk activity (except at the beginning and
maybe at the end), it seems to be done completely in the cache.

Thanks,
Marcus
