A cryptographic identitifier of the Sugar user, randomly created at
first boot and stored in files;

.sugar/default/owner.key and
.sugar/default/owner.key.pub

Delete it using rm, as it says here;

"Otherwise the cloned laptops won't be able to collaborate using activities, or 
the wrong names will be shown in Chat,"

Which things are truly important depend on the circumstances, and only
the teacher will know.  For instance, without deleting the identity
key the activity collaboration feature will fail in strange ways.

OLPC OS on the XO is configured for ownership style "one laptop per
child".

If you always want to delete the child's Sugar name, you might either
change login scripts to delete it before starting, or assume a
default.  It simplifies getting started into a class.

e.g. in the OLPC OS 16.04 live build on the NL3, we have this in
/usr/bin/sugar;

gsettings set org.sugarlabs.user nick 'You'
gsettings set org.sugarlabs.user gender ''
gsettings set org.sugarlabs.user birth-timestamp 689659403
gsettings set org.sugarlabs.user group-label 'Adult'
gsettings set org.sugarlabs.user color '#808080,#c0c0c0'
gconftool-2 --set /desktop/sugar/user/color --type string '#808080,#c0c0c0'
gconftool-2 --set /desktop/sugar/user/nick --type string 'You'
