Thanks to all who responded about netatalk on rpi buster.  It turns out that I
need random number exchange (uams-randnum.so) which isn't supported in the
buster repo of netatalk.  So I need to build/compile netatalk from debian
source.  No luck yet.   '
sudo checkinstall --fstrans=no' fails at the following line:

ar: /home/pi/netatalk-3.1.12~ds/libatalk/acl/.libs/libacl.a: No such file or
directory

It looks like an archive file is missing.  libacl.a does exist in 
/home/pi/netatalk-3.1.12~ds/libatalk/acl/.libs/libacl.lax/libacl.a but is
empty/null/0 bytes. [Note the extra directory level libacl.lax]  Copying the
directory up one level to .libs does 
not help and is deleted on the next execution of checkinstall. 

Has anyone sucessfully compiled netatalk for a raspberrypi?  Any hints on what
to try?  I am using instructions from "agrlh/install_netatalk_debian.md" for a
RaspberryPi TimeCapsule.
