Here is an example of what I suggest interested parties can do quite
easily. Modify the source package as in the attached example patch. This
is not an example of a full solution, just a quick and dirty hack to
build octave with no graphical dependencies. Note that this will also be
a slightly crippled octave without any imread or imwrite capability.
With the resulting packages, I can compare the storage requirements in a
clean minbase installation:
# apt install --no-install-recommends octave
…
0 upgraded, 181 newly installed, 0 to remove and 0 not upgraded.
Need to get 88.3 MB of archives.
After this operation, 450 MB of additional disk space will be used.
versus
# apt install --no-install-recommends ./octave_4.2.1-6_amd64.deb \
./liboctave4_4.2.1-6_amd64.deb \
./octave-common_4.2.1-6_all.deb
…

Need to get 29.9 MB/38.9 MB of archives.
After this operation, 167 MB of additional disk space will be used.
So I have saved about 280 MB in storage by dropping all graphical
dependencies. That's about 5 MB in the octave binaries themselves and
the rest in the dropped dependencies. Octave will not have a GUI, will
not be able to plot anything, and will not be able to read or write
image file formats.
Is 0.25-0.3 GB on the order of the savings you are looking for? Is it
worth not being able to work with image files or plot anything, even
headless plotting?
