System is Pine64+ with Allwinner A64 SoC.
Fedora 32 is booting and running on this sdcard based system. However it is using a very
small part of the 64GB sd card. I am looking for suggestions on how to utilize the
non-partitioned space. Manjaro seems to have a script to resize the root partition and
incorporate unused space into the system. Alternatively I could create a new partition and
file system. This would be handy for the home directory. How do we turn my existing home
directory into a new one with its own partition?
There's an option for arm-image-installer called --resizefs that
expands the root filesystem out to the size of the card. You likely
want to expand the root fs a little bit if you add a separate home but
that use case isn't handled by arm-image-installer but you'll find
lots of options for doing this if you google, it's no different that
any other linux system in that regard, it's not arm specific.
