You can add a suffix like normal sites:

MASTER_SITES=	${MASTER_SITE_IDSOFTWARE:S|$|et/linux/:site1|} \
		${MASTER_SITE_IDSOFTWARE:S|$|et/:site2|}

DISTFILES=	distfile1:site1 \
		distfile2:site2

The .3 is right, but it is not needed.

If show me a better order (like faster sites first) I will change it.

I think this problem will be solved with the previous example.
