As a point release i’m not sure why VMware decided to completely change the layout of files on the CD ISO along with change various system files, however they have. I suppose one change is beneficial as it improves the method for creating a USB stick which for previous versions of ESXi is documented here. They have also changed console access and ssh access to the hypervisor, which now can be enabled from the orange console screen under TSM (technical support mode) settings.
Writing to a USB stick:
Now the iso contains a simple file called imagedd.bz2 that is found in the root of the iso, which just need bunzip to decompress it and the dd’ing to a USB stick as documented before.
At the moment there is nothing about this on the internet so it was a case of going through a few files to find it, but previously /etc/pam.d/common-password contained all of the password complexity requirements as documented on the VMware KB. However now all of the password requirements are located in the file /etc/pam.d/system-auth, so this file will need editing if you don’t want insane password requirements for all users.
