It's now possible to specify a disk to be used for Talos Linux's "EPHEMERAL" partition when applying configuration to a server. Note that this is the partition mounted under
/varwhich contains local Persistent Volumes. So the name "ephemeral" can be confusing / misleading.We can even support RAID devices for this partition, though they require the mdadm extension and you have to create the array manually before bootstrapping. You will also need a minimum of 3 disks for RAID to work since the install disk can't be RAID'ed and therefore must be separate.
