You can use the _jed_save_buffer_before_hooks to raise a question if
saving the file should really take place.

#v+
define ask_before_save(file)
{
    variable stat = stat_file( file );
    if ( andelse {stat != NULL} {stat.st_mode & 0222 == 0} 
           {system("test $(id --user) -eq 0") == 0} )
       error("You try to save a readonly file as root");
}
#v-

Regards, Jörg.
