Re: tramp (2.5.0-pre nil/nil); Cannot write to /sudo::file in /boo t partition

[Yikai Zhao]

OK I think I got it:

# sudo cp -f -p init.el /boot/init.el 
cp: failed to preserve ownership for '/boot/init.el': Operation not permitted

cp returned non-zero code because the FAT filesystem (/boot) does not support 
file ownership etc (required by the -p argument). However the file actually get 
successfully copied.
