No tangent here. I also use Sabayon, which is a Gentoo product, and the directories are almost in the same place. The UEFI is something I pulled of the net. I'm not running Fedora and don'r plan to but I do have Centos installed on a few machines.
Sounds like you deleted the root partition but didn't delete the others. you can fix your grub menu as follows:
Refresh GRUB configuration on a BIOS system:
# grub2-mkconfig -o /boot/grub2/grub.cfg
Refresh GRUB configuration on UEFI systems:
#grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg...
The question is do you require the data that is on the non-free partition? If you don't require the data then delete the partition and you will have the whole 1TB to use. If you do then you could try and squeeze the data partition.
OK here the thing you have to remember in order to get full Jumbo packets from point to point everything along the path must support jumbo frames. If just one device doesn't you'll never get jumbo frames working.
Orange, to be honest I think the kernel is way above your abilities at this point and you should focus more on learning the OS and how it is put together so you'll understand the kernel and what is and isn't included a lot better. You're going about this sdrawkcabssa.
I can tell you from...
With GParted you just erase the partition and create a new one Then you can size it as big as you want. Then when you install a new OS tell it to use the partition you created.
Is 172.16.0.2 part of your DHCP scope? If it is why not simple reserve that ip for this device? If it's not why not set the IP Address statically on the device itself?
