SLES 15 LVM + XFS Without Separate /boot Partition

Image

That's when I switched to rootless Docker — and you should too. Rootless Docker runs the Docker daemon entirely under your regular user account. No sudo required. No root privileges for container operations. If a container gets compromised, the attacker is stuck with your user's permissions — not root. You asked, I delivered: This guide was the #1 request in my LinkedIn poll (Ubuntu/Linux Mint won with 50% of votes). Planning Disk Space In rootless mode, Docker stores all images, containers, volumes, and build cache under your home directory at ~/.local/share/docker . This means your home directory needs enough space to hold every...

pfSense and scp

pfSense and scp doesn't play nice. When you try to scp to admin@pfsense.hostname you will likely encounter the error " Illegal option -[X] " The solution to this is rather simple too, when running scp to pfSense, just use the root account.  Cheers
