<me raises a hand>

Incidentally I use NFS to a file server on my laptop, over wifi, and I close the lid 
for the night. It's NFS mounted soft.

If it was mounted hard I wouldn't expect the lid close event to result in a 
successful suspend if wifi went down - but with soft I would be pretty sad in the 
morning if batteries drained if I closed the lid after there's a power outage which 
took down both wifi and the laptop power supply.

Closing the lid while on battery is a pretty strong command from the user.

Arguably this is a special case on several levels as on desktop distros it's not at 
all easy mount NFS shares (all point & click automation goes to Samba shares), just 
wanted to mention it.

Thanks,

	Ingo
