This was a huge disappointment at the time and in my mind called into question the technical judgement used in the rest of the product. Seems like nothing has come of it and tbh I had forgotten all about it.

Yes, mostly. You get some challenges with booting, however. Some machines allow you to interrupt boot up and select an alternative boot drive, while others (particularly Windows-based) want to own the machine and make it more difficult to do so. I don't have a great deal of experience with Windows and it might have gotten easier in more recent versions to do this.
Regarding portability, Linux distributions handle changing the hardware out from underneath them pretty well, but things like hardware device names etc. changing might disrupt some configurations.
Absent more complex solutions like virtualization, dual-booting is typically the easiest and best option. Then one day you stop booting into Windows are are free 😏

2024-06-24 15:09:35

I have a great deal of experience with this, and I'd highly recommend against it.
First of all, the endurance of USB drivers is very poor; most retail flash drives are designed for light weight storage of files with occasional updates and accesses, not the continuous hammering a drive gets during live OS operation. It's quite easy with continuous live OS operation to "burn out" a flash drive.
Secondly, typical OS configurations write to log files and update packages, etc., so the persistence space tends to fill up faster than one might expect.
Both of these are less of an issue with external hard drives connected over USB, either spinny disks or SSDs. But at that point you can do a full OS install onto the external disk and boot from that rather than using a live distribution. I've done this and it works well, though the USB speed becomes a big limitation.
There are other solutions that involve more work such as virtualization (running either linux as a VM on Windows, the reverse, or full virtual environments like #proxmox), but require more technical knowledge and administration.

Voting is deliberate consent to the outcome, explicitly granting your sanction to the status quo and the system of threats and force against you and others that back it up.
It is difficult to argue against the injustices stemming from the people ruling over you when you have participated in and perpetuated the very thing that gives them oxygen.

If you're not familiar with ZFS, it has a variety of disk redundancy options, equivalent to the traditional RAID 0, 1, 10, 5, 6, and 7, but done in software and integrated into the filesystem instead of using a hardware controller. It basically boils down to a tradeoff between how much storage space you want to sacrifice to redundancy and how many drives can fail simultaneously.
RAIDZ2, for example, allows two drives to fail without data loss (while you go replace those drives!)

The convenient fictions about the world that are taught to children become held so dearly they hinder seeing things as they really are as adults.
When navigating life armed with only the knowledge instilled in you by your parents, tribe, church, school, or government, you end up only serving their agendas, not your own.
Question everything. You may end up right back where you started, reinforcing your worldview, or you may discover uncomfortable truths that you can no longer avoid and change your mind about many things.
Either way, you'll own your own mind, no longer relying on the inertia of your upbringing.
