What is the best way to seperate routing tables in Ubuntu?

I'm building a lab environment with multiple routing devices and 2 Ubuntu machines as clients (22.04.2). The ubuntu machines need to act as 8 independent clients (from networking point of view) because the core network is separated by VRFs.

The ubuntu machines connect to a switch which separates the traffic with 802.1Q trunking so these clients will receive traffic on multiple different VLANs. My ...

Point /var to another SSD during installation and keep data
tr flag

I have Ubuntu 20.04.6 installed on two SSD drives:

  • ssd1 holds all in / and boot partition.
  • ssd2 points to /var and stores data

Now I would like to install fresh 22.04.2 distro, but I would like to point /var of the newly installed system to ssd2 as well. During this process I need to keep all the data in /var as it contains important data files.

How do I do so during installation?

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
