Is this an error?
groupadd -g 42000 share
chown nfsnobody /home/export <----- I get an error with this line.
The user minimal-access user may be "nfsnobody" or "nobody", the distributions may use either one. Check your /etc/passwd file to confirm.
Thank you for pointing this out it will be corrected. Could please verify which distribution you are using?
I am using Raspberry Pi OS (Debian Buster).
