In +# addition, there was and is still no conversion guide to convert a +# 32bit Parabola installation to 64bit), and in some cases (lot of +# self-built software in /usr/local, PostgreSQL database, etc) the +# migration to 64bit requires some work. +# +# As for using i686 for new installation on x86_64 computers, it can +# enable people doing that to find and fix bugs on Parabola i686 to +# enable people with 32bit-only computers (like Libreboot compatible +# I945 Thinkpads) to still be able to use Parabola. +# +# Having both architectures (arm and x86) in the same PKGBUILD enables +# to more widely test this package (if we find issues on x86, they'll +# most likely apply to arm as well).

So modules for linux-libre-64 need to be added +# (like tp_smapi-64) and dkms packages need to be adapted to also +# work for this kernel. +# - Some software (like building Guix) break with 32bit rootfs and +# 64bit kernels due to wrong assumption about the number of bits, +# through other software (like building rust with mrustc) work +# better (here because we have 3GiB instead of 3GiB of memory per +# process).
