You mean
   if [ "x$(FOO)" = "x" ] ...
?

Yes, we could source out the complete linux/hurd kernel-adding blurbs 
into an external shell library that is shared with 10_* and 30_os-prober.

However, please don't forget these are two different things. 10_* look 
on / and /boot, while os-prober looks on all *other* partitions.

Not a concrete plan yet, However, we should first get thinks *working* 
before we care about cosmetics, IMHO. ;)

I asked myself the same question before. I seems like os-prober does 
not support any of the BSD flavours, which sounds strange since it 
even discovers Solaris on i386.

Should be a bug against os-prober.

Definitely. I'll add a short warning message.

Furthermore, I am going to modify the script to immediately 'exit 0' 
if it turns out it misses the tools required to update the boot menu 
(i.e. os-prober, linux-boot-prober, grub-probe (>= 20080228)). These 
tests are spread all over the script at the moment.

Best Regards,
Fabian

PS: Shouldn't 30_os-prober be an upstream feature of os-prober?!
