Hi again Walter and all Lubuntu users,

Well, yes, almost like that. The *alternate* iso does not use zram, so
it was enough to wipe [the first megabyte of] the internal drive and
create a new partition table. I did that before booting into the
alternate iso file, but it could be added into the alternate installer.

Then select No (when asked to install grub, the bootloader) and enter
/dev/sda manually ... and success :-)

I have a good Lubuntu installed system with swap and everything works
(except maybe the Lubuntu Software Center, which I have never used).

*Summary*

This Lubuntu Vivid 32-bit alternate iso file is in rather good shape.
With a little bit of help it can install a good encrypted LVM and
encrypted home system. It should be possible to make the installer wipe
the first megabyte or the whole drive (a user choice), and then create
an MSDOS partition table before starting the advanced partitioning.

Best regards
Nio
