How many hosts have you installed using fai? Currently more than <b>3000 hosts</b> (mostly physical, 10-15 VM), over
the past ~12 years, we certainly used fai certainly way more than 10000 times to install machines.

Which version of fai are you using? Currently migrating from 5.3.6/jessie to <b>5.9.1/buster</b>
Which version are you using as your install kernel? plain Debian, usually from backports

Which types of hosts are you installing with fai? we only have servers/compute nodes
but with the exception of the fai server itself, more then 99.9% of
the machines are fai installed. Maybe we will fai.me the fai server.

How do you boot your hosts? First via network/DHCP/PXE (still no UEFI) for installation, then via localboot.
Does the default install kernel recognize all your hardware? Usually yes, if not we go for the backports kernel.
Do you manage your configuration space under version control? Yes, everything in there is in git (as well as /etc/fai)

How big is your config space (Mbytes, # of files)? 205 files summing up to less than 1 MByte
How many files do you have in ../config/files? 27
What types of scripts are you using for local customization? saltstack

<b>What is the business of your company/organisation?</b> fundamental research, <a href="https://www.aei.mpg.de/atlas-cluster/">Max Planck Institute for Gravitational Physics</a>

Are you using the FAI.me build service?
As a trial/template for a few virtual machines.
<br><b>Additional comments:</b>
fai is nowadays only used for the bare minimum installation, after the
first reboot our saltstack configuration takes over, i.e. we never use
fai softupdate

Rarely, we use it as a live boot environment

More hosts will com soon:
44 hosts each 8 V100 or RTX 2070Super GPUs and
444 hosts each 2x32 Core AMD Ryzen2 and 512 GB RAM :)
