No, there isn't a cache, it reads /etc/krb5.conf every time the script
is run. The two files do seem identical, but the script checks if the
file exists, checks how many lines (should be 4), is there a
'[libdefaults]' line, what REALM is being used, is 'lookup_realm' set
to 'false' and is 'lookup_kdc' set to 'true', the krb5.conf should only
be displayed if at least one of these is incorrect.

This must be coming from a 'samba-tool' command and the 'samba-tool'
commands should only be run a DC and you need ALL the samba packages.

Well, Louis wrote the original script for debian, but I use Devuan and
there is little in the script that relies on debian, mostly it is just
'what is this script running on' ;-)
