Ah-ha!

Are you using the timestamp feature I added? If so, I would first
compare timestamps of your running system and of the image you built.
cat x2go-tce-timestamp in the builddir vs. the build number you see at
the local or ssh login prompt (cat /etc/issue, bottom line), or, lacking
the timestamping code in your build, comparing the output of

# in the builddir
TIMESTAMP=$(stat -c %Y ./config/includes.chroot/lib)
HUMANTIMESTAMP=$(date --date="$TIMESTAMP")
echo "Build Version: $TIMESTAMP ($HUMANTIMESTAMP)"

# in the booted TCE
for TIMESTAMPFILE in /lib/live/mount/rootfs/*/lib; do
 TIMESTAMP=$(stat -c %Y $TIMESTAMPFILE)
 HUMANTIMESTAMP=$(date --date="@$TIMESTAMP")
done
echo "Build Version: $TIMESTAMP ($HUMANTIMESTAMP)"

Because to me, it sounds like you're not booting the image you're
expecting to boot. Maybe you're storing it to the wrong directory, maybe
the client you're testing with has a custom PXE boot entry that causes
it to boot the image from a different location, maybe your USB media is
actually a bootable X2GoThinClient because you were experimenting with
that, and you're booting off of USB rather than PXE, ...


Did you try using the entire build script from the wiki page, or only
patch the automount script?
What happens when you try to build a stock image using our scripts, our
git repo, and no custom changes?

I just checked it myself on a stretch amd64 build, a stretch i386
(686-pae), and a jessie i386 (686-pae), the package is always there,
just like it should be.

Of course, if all else fails, you could run unsquashfs, chroot into the
resulting directory, install the package manually, then run mksquashfs
again. I would suggest adding options
-comp xz -Xbcj x86 -b 1024K -Xdict-size 1024K
to mksquashfs (based on a suggestion by intrigeri from the TAILS team),
and reading the man page for mksquashfs first.

Kind Regards,
