These changes look ok. The only thing (just a consistency nit) is that
I would choose a consistent way of incrementing in loops, i.e.

i=$(expr $i + 1)
: $(( i += 1 ))
i=$(( $i + 1 ))

e.g.

$ cat increment.sh ; sh increment.sh
#!/bin/sh

set -x

sh -c 'i=$(expr $i + 1); echo $i'
sh -c ': $(( i += 1 )); echo $i'
sh -c 'i=$(( $i + 1 )); echo $i'
+ sh -c 'i=$(expr $i + 1); echo $i'
1
+ sh -c ': $(( i += 1 )); echo $i'
1
+ sh -c 'i=$(( $i + 1 )); echo $i'
1

On the other hand, if it's all going to be converted over to ATF in
the near future, it doesn't really matter :). If you (or Peter) commit
the work to isilon-atf, then I'll do the work required to convert it
(minus the libutil testcases -- these need to be merged into what's in
isilon-atf from NetBSD).

Thanks!
