Well my "dear" embedded system doesn't have libc :-(
So 35664 saved in kernel (less on disk), requires 25212
extra for hdparm + more for static linked uclibc (hope
it works ;-)). As a side note if this happens hdparm would
be a requirement for busybox IMHO, anyway getting back on topic...

All the info I've ever needed is /proc/ide/hdx/capacity
which I could get from /proc/partitions with more a bit
more effort, so I vote for removing /proc/ide.

I think everyone realises Martin is doing great and much needed work
on IDE (btw I'll have those flash support patches soon Martin ;-)),
but I did think this change needed debate. In general I know it's a
hard decision what to export in proc, especially if there are
existing dependencies, a few already mentioned possibles in RH7.1:

/sbin/mkinitrd
/sbin/fdisk
/sbin/sfdisk
/sbin/sndconfig
/usr/sbin/mouseconfig
/usr/sbin/kudzu
/usr/sbin/module_upgrade
/usr/sbin/updfstab
/usr/sbin/glidelink
/usr/sbin/sndconfig
/usr/lib/python1.5/site-packages/_kudzumodule.so
/usr/bin/X11/Xconfigurator

For e.g. could the same arguments could be made for lspci only
interface to pci info rather than /proc/bus/pci? The following
references are made to /proc/bus/pci on my system:

/sbin/lspci
/sbin/setpci
/sbin/sndconfig
/usr/sbin/mouseconfig
/usr/sbin/kudzu
/usr/sbin/module_upgrade
/usr/sbin/updfstab
/usr/sbin/glidelink
/usr/sbin/sndconfig
/usr/sbin/adsl-config
/usr/sbin/internet-config
/usr/sbin/isdn-config
/usr/lib/python1.5/site-packages/_kudzumodule.so
/usr/bin/X11/XFree86
/usr/bin/X11/pcitweak
/usr/bin/X11/scanpci
/usr/bin/X11/Xconfigurator

cheers,
Padraig.
