can u explain this?
* Improved language support by auto loading locale support extension(s) when both "lang= " and the "-locale.tcz" extension(s) are available in tce/optional.
is this working while booting or also when the system is already started? tce-load...
Yes, it works both on boot and when using tce-load.
Example: boot tinycore lang=it_IT@euro
tce-load -i /tmp/tce/optional/atk.tcz
if atk-locale.tcz is in /tmp/tce/optional, it will be loaded as well.
