This particular block of code appears unnecessary (since
$padding is unused).
I must be missing something, because I'm pretty sure it's used..
What did I miss?
+ paddingsize=$((60 - $namesize - $rc_argsize))
+ until [ 0 = ${paddingsize} ]; do
+ padding=" $padding"
+ paddingsize=$(($paddingsize - 1))

For safety, the conditions should probably be [ 0 -ge
${paddingsize} ] I don't see any alternative to the until loop.
If efficiency turns out to be a real issue then you could try
doing the expansion in multiple goes. Eg:
until [ 8 -gt ${paddingsize} ]; do
padding=" $padding"
paddingsize=$(($paddingsize - 8))
done
until [ 0 -ge ${paddingsize} ]; do
padding=" $padding"
paddingsize=$(($paddingsize - 1))
done
Thanks for the hints. I was testing the same changes to the
namesize/etc as you suggested, and it does work and is more
readable and more efficient.
I've included your suggestions and put the latest changes here:
http://www.googlebit.com/freebsd/patches/rc_fancy.patch-3
Patch -3 is working good here. :)
best regards,

PS: next try... fancy_color_rc="YES" ;)
If I could figure out how to make sh do colors, I'd do it. :)
Is that all? :)

But can you do it without the printf's? That's the key. We don't have
printf until later in the boot process..
