Isn't it difficult to setup?

So what if they continue to refuse to work after that if the contract is bad? Police are going to force them to work? Isn't that slavery?

Question: How to merge 2 btrfs partions using subvolumes? in c/btrfs@lemmy.ml

[–] narF@lemmy.ca 1 points 2 months ago

What I ended up doing:

Moving the root partition from one partition to the other, using btrfs send | btrfs receive
Updated fstab to use the correct partitions
The computer kept using the old root partition then booting, I had to use ubuntu's boot repair (https://help.ubuntu.com/community/Boot-Repair) to fix that
I probably should have moved the home partition instead of the root one. I would have avoided much trouble.

My understanding is that trams are much more cost effective long-term than buses, because the rails last much much longer than asphalt or even concrete.

They also have other benefits:

Smoother, less bumpy ride
Bigger capacity than buses, with the possibility to add up to 5 cars
Don't have to wait at traffic lights (We can install sensors to detect a tram is coming and switch the light so that it can go ahead without waiting. That's technically doable for an BRT/SRB, but it's more complex and as you can see, they didn't do it for SRB Pie-IX...🙁)
Less noisy
Easier to electrify
Easier to automate (make them self-driving)
No tires means less pollution
Grass can be added between the 2 rails, making it more pleasant looking, absorbing heat and noise
Level boarding make them more accessible
and more

Can I do this while the system is running? I guess it would be safer to boot to a liveUSB before attempting this?

Also, what do you mean by "After a rebuild of the initrd" ? That's something I have to do after editing fstab? How do I do that?

Hi! I'm learning how to use btrfs and I need some advice.

One one of my desktop, I made the mistake of creating 2 partitions, one for /(root) and one for home. Both are btrfs. I didn't know that I could use subvolumes so that they could share the same physical space.

My question: How can I merge the root and home btrfs partitions into only 1 partition that would use btrfs subvolumes?

I'm looking for something like that:

Partition1 (btrfs)
- subvolume 1: @root (mounted to /)
- subvolume 2: @home (mounted to /home)
Partition 2, 3, 4...

My current setup:

1 physical hard drive (1 TB), shown as sda below
The partitions I want to merge are sda7 and sda8
That computer is an iMac also running MacOS so it has a few other partitions that I should not touch
