SharePoint - Language Packs

In what order does one update when including Language Packs? With Service Packs? With Cumulative Updates? It used to be confusing. Now with 2010 it is straightforward.

Get the language packs:

now update your farm as desired.

1- SP SharePoint Server
2- Language packs
3- CU SharePoint Server
4- PS Config (on every box)

done.

NOTE: if you go and add a new language pack afterwards, you must reapply the CU as it may include updates for that language pack. (and rerun PSconfig again, of course)
