The best skewed distribution could be your own, so we may get the horse

I think running a few find -size commands would

Right. Of course one might just use
Hi Everyone,
I just put on SuSE SP3. When I IPL'd, it gives me these messages:
Loading module dasd_mod dasd=$dasd ...
insmod: dasd_mod: no module by that name found

Agreed. I looked at /etc, which has a lot of small
files and the average files size was 5900 bytes - not
a goot candidate
However, I could not
recommend ext2 as a filesystem because it is too
easily damanaged (sic)
How so?

The Linux file systems are heavily cached and allow
dirty writes of the data - i.e., the data in memory
is not immediately synced with the hardware copy. This
is controlled by the
Sorry for pushing this into the ground, but I'm still
bothered by the it depends response for using 1K
blocks on eckd devices. In the various file systems
I've seen on various platforms, 1k blocks are only
useful for very small files with none of them very
big.
So, to quantify this, I did some
