Ah, but I didn't say that I had a problem :-) Yet! This is today's job.

What I would like to know is whether this is a genuine requirement for 
IPW2200 and why. In other words, I want to understand why this is 
necessary.

Since /sys is synonymous with /sysfs, and since /sysfs isn't created by 
default during a sarge install and by a further upgrade to etch, then 
this mount seems to be a random an unnecessary event. If it isn't, then 
I'd like to understand why. Reading man sysfs, it says that with the 
proc FS mounted on /proc, then the same information can be derived from 
/proc/filesystems.

A quick cat on that shows not only sysfs, but also usbfs and tmpfs, 
which I've also heard quoted as being necessary. /sysfs (not sysfs) 
appears to be deprecated, but, as I said, I'd like to be clear what is 
occurring here.

I can see that there is a package, sysfsutils, that provides tools to 
query this VFS.
