Hello,
In the NTFS file system, under the security option in a folder's properties, there is an advanced option where a user/group can be restricted from writing or deleting existing files in the directory but at the same time can be granted permission to create a new file or folder. So while existing data on that folder cannot be edited or deleted, the user can paste new files in that folder.
Apart from enabling ACLs on ext3, for the specific scenario you mentioned, adding the sticky bit on the directory achieves this. /tmp has this attribute set so that any user can create files there but cannot delete files which belong to others.
Can such special permissions be granted in EXT3 or JFS file systems? On the net I find that advanced ACLs mainly have 3 options of read write and execute. If write permission is granted, user will delete files. Without read permission, user cannot paste new files.
