The best way to use SD-Cards in Linux only environments is to format them with f2fs file system. f2fs was developed by Samsung with internal behavior of embedded MMC memory devices in mind. Which is pretty the same like an SD-Card. With f2fs you also have
uid/gid as usual and it will help to improve the endurance and
performance of an SD-Card.

Integers are also limited to 31 bit:
(expt 2 31) => -2147483648
in contradiction to https://islisp-dev.github.io/ISLispHyperDraft/islisp-v23.html#integer_class
