Actually I am using a single-service VM, but blowing away a VM just because I want to demote/promote feels like overkill.
For step 3, since I’m running from source, does that change anything?
re: step 4 I plan to edit the existing /usr/local/samba/etc/smb.conf and krb5.conf files, but if you think this is a bad idea then I’ll rebuild them.
