yes that's the problem of symlinks, symlink exists but it point to nothing (no file) that's why a 'dynamic' symlink must exist , let's call this alias?! :) alias can be offline or online update offline - file online - owfs, owserver file update (echo text > alias_file) this could be nice use not on network device alias could exists too, but must be in a file at rootfilesystem or another 'special' file like '/alias_compiled_file' this one is the alias 'tree' of inside owfs code maybe a alias array with 'primary key' alias name, and sensor id as values, we could only have one alias name, but we can have many alias pointing to one sensor id it should be dinamic array (vlist?) with malloc? or another dynamic memory alocation lib > >> maybe a other directory >> /all_networks_sensors/ >> without directory of ds2409 and per directory sensor >> a 'ls' here make a big search on all networks > > I was also thinking to a directory per type (ie all DS18B20 in > one directory).
