Hi,
in my work lzma lib can help only for mkulzma utility.
geom_ulzma use internal lzma, because kernel don`t have lzma
lzma encoder for compressing kernel for CFE loader use old version of lzma \
(archivers/lzma PORTVERSION= 4.17)

But I would be very happy, when supported archive types in tar and libarchive maybe \
customized with options like WITHOUT_BZ2, WITHOUT_LZMA ... .
