Nano version greyed out for download?
Why is the nano version greyed out? I just want to download and run the latest version of pfsense from USB drive without a physical hard drive. Any insight is appreciated. Thank you.
Nano is EoL, it hasn't been updated in years and hence is no longer considered secure.
You can boot from one USB stick and install to a different one if you need to.
Be sure to remove swap during the install and then move /var and /tmp to RAM drives once booted. Also check the root is mounted noatime, you may have to edit the fstab if it isn't. Doing those things should prevent the USB drive being killed by writes in a short time.
Thank you Steve for the insight. That was very helpful.
