[ILUG] dd weirdness

[Paul Jakma]

why does:

	dd bs=1024k count=150 seek=150 if=/dev/zero of=var_fs

give me:

	[paulj at doohan host1]$ ls -lh
	total 176M
	-rw-rw-r--    1 paulj    paulj         50M Oct 12 17:10 swap
	-rw-rw-r--    1 paulj    paulj        300M Oct 12 17:13 var_fs

(the swap file was also dd'd - i wanted 25M). It also happens with 
bs=1M.

weird...
