Are there any errors in my Gentoo command list for my first installation?
 
Hello gentoomen, I am transitioning from Arch to Gentoo on my new rig and with the combination of systemd + LUKS/LVM, and being my first time, I knew this would get confusing so I spent some time trying to plan it out.

Now I ask of you to peer review it and help me ascend on my glorious journey, any suggestions or recommendations are welcome. Thank you.

This is for: UEFI, Ethernet, Luks on LVM, and systemd.

Hardware:
  • Intel i7-6700k
  • Nvidia GTX 980TI
  • 16Gb RAM
  • Samsung 500Gb SSD
  • Western Digital 2Tb HDD

Here is my game plan:

Device Graph

Mount Graph

*Slightly different from pics (eg. /boot/efi)
  • Encrypted LVM vgs w/ keyfiles
  • SSH (or VNC)
  • Decrease boot time
  • Mail Server
  • Gaming Rig
  • Bitcoin mining
  • WM ricing

___________________________________________________________________________
Parts that I know are wrong and I need guidance for:
  • saving keyfiles
  • Installing systemd instead of OpenRC.

Edit: After adding in the systemd componenets I am 100 uncomfortable with how this is set as it feels mangled.

___________________________________________________________________________

Edit: Added tmp to fstab, added systemd kernel config, changed initramfs, added LVM daemon, added systemd to GRUB2 config, added root & user passwd, added hostnamectl commands, added systemd installation, added systemd-networkd, removed /tmp as systemd automatically sets it, added Activating lvm, added updated systemd requirements, added VIDEO_CARDS variable to make.conf, removed init & boot config, system loggers, and cron daemon sections, switched the hostname for hostnamectl commands, switched networking config commands.

With a good UEFI Bios, you dont need a FAT32 partition.
Just use ext4 for all partitions and you dont need an additional encryption - since ext4 is encrypted by default with a keylenght, which is save (cant be decrypted by an quantum computer).
I would not use LVM.
Compile ext4 support directly into the kernel.
FAT32 support as module for USB sticks and CF cards.
Support for optical discs (CD/DVD/Blu-Ray) as module.
Add graphics driver for your over-powered card.
SystemD for minimal boot time and choose the background services depending on the system.

And: interesting graphics.
