Hmm. Seems I am in neither group.

I use cat /proc/pci for the same reason I use cat /proc/scsi - when
configuring a box, or adding new hardware, to figure out what I should
look for and where it is.

I don't particularly care which part of the file system this omes from,
but I do care about being able to find it quickly, and about it being easy
(i.e. not need looking at 7868 separate files) and giving the essential
info (which is the info that can be found in the relevant docs or be fed
to google).

I seriously distrust tool-based solutions for this. It is far too likely
that any new tool will be missing when I most need it, and old tools
already aren't a particularly convincing solution.

I don't want to grovel through 7868 tools just as I don't want to grovel
through 7868 files. And the more those are, the less likely I am to even
have heard of them - from the lsXXX tools, the only one I knew about was
lspci, and lsusb (which seems to be the other one actually installed)
seems to be a lot more reluctant to give useful info to the non-USB-
expert.
