ln5: 2022-03-24
   Last week:
       - Received hardware for a new home for snowflake.tpn; discussed OS configuration with dcf in private email
   Next week:
       - Install Debian 11 on new snowflake.tpn
       - Possibly rack new snowflake.tpn, if I can get access and find time to do the transportation
   Need help with:
       - Input on urgency appreciated, for my planning
       - Input on preferred CPU configuration, esp wrt HyperThreading -- lacking input before deployment in data centre, the machine will *not* have HT disabled and CPU bug mitigation will thus have to be carried out by the kernel
