A friend of mine has one directory (/var/mail) on his Linux machine where rm seems to truncate files if he has no write permissions on the directory. I like this feature and wonder how could I do the same on my Linux box?This is the behavior what I want:$ mkdir /tmp/nase$ echo something > /tmp/nase/bla$ chmod ugo-w /tmp/nase# ...do some more tricks with /tmp/nase ...$ rm /tmp/nase/blarm: cannot remove /tmp/nase/bla: Permission denied# but the file is truncated now:$ stat -c '%s' /tmp/nase/bla0On my friends machine /var/mail is an NFS mount with these permissions:drwxrwsr-x  2 root postdrop 4096 Dec  8  2005The NFS server is probably a SUN machine.One more general technical NFS question: Does the permission denied error come from the client only or from server?
