<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
