how does the copy cp command differentiate between the ESP and root partition?












0















the boot directory exist on both the ESP(sda1) and root(sda5) partition.



when i use this sample command to copy vmlinuz and initrd files:



sudo cp -a initrd.img-4.15.0-43-generic /boot



i was able to get the system to boot and thought i had copied the file to the ESP. i also checked the root partition after using the command and confirmed it does not exist.



however, after a few days, i discovered the files had appeared in the boot directory of the root partition.



before that, i had also manually moved the files to the boot directory of the root partition using a file manager(dolphin) but was unable to get the system to boot.



so i would like to ask what is the command to copy files to the ESP partition, and the command to copy the same file to the root partition? basically, i would like to know how the linux system differentiate between the ESP and root partition for the same sets of command, i.e, cp, mkdir..etc



thanks

          Accessing regular linux commands in Huawei's Dopra Linux

          Image
          4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
