Linux Notes for Dell Precision 7550

I bought this laptop to replace my nearly 10-year-old personal machine that finally died due to a failing display. It was already three years old when I bought it, but it had everything I wanted at a price I couldn't refuse. (Black Friday.)

I guess this is as good a place as any for a side note: I bought this laptop from dellrefurbished.com. Note that I don't recommend buying from them due to the exceedingly poor quality of support that I received. They have permission to use the Dell logo and branding for their business but they are NOT Dell and you do NOT get the standard Dell support or warranty. If something is wrong with the laptop, they will NOT offer to repair it. Instead, they will only offer you a very low token partial refund. I would say if you are going to buy from them, these are the things to keep in mind:

  • Their normal warranty is essentially worthless, so do not buy their extended warranty either.
  • Even if the laptop is listed as being in "A" condition, that only applies to the cosmetics

                Linux: Mounting a filesystem with a UUID/PARTUUID
              
          

        

      

        

  

      

    
To get the UUID of a block device, use blkid:


$ blkid /dev/sdb1
/dev/sdb1: UUID="1c46a3c1-cbe7-4bb6-a412-445f317e2b5d" BLOCK_SIZE="4096" TYPE="xfs" PARTUUID="7f943a21-be92-304f-8bae-45aa7c4b0c78"



There are typically two UUIDs given, UUID and PARTUUID. UUID is a property of the filesystem, while PARTUUID is a property of the GPT partition table. In a lot of cases, you can use either/or but keep in mind your future use cases before settling on one or the other. For example:


    

  • If you might be cloning a filesystem on the same host, this will result in a duplicate UUID but not a duplicate PARTUUID. If there are two filesystems with the same UUID present on the system, Linux will refuse to guess which one you mean.
