Noted during a Swedish text-mode install:

In the "select installation type" screen there are four choices:
"Workstation", "Server System", "Custom System" and "upgrade existing
installation".
The "workstation" and the "upgrade existing installation" strings/options
are translated, but not the "Server System" and the "Custom System". The
"Server System" string isn't even in the translation pot file. The "Custom
System" is, but appearantly it's not being used.
It would be nice if those two strings could end up being translated.
