Simple Gentoo installation.
Simple partitions for new Desktop users. Common problems with Gentoo installation.


I am not super nerd. I spend several days for sex with UEFI and GTP.
We will create partition table "dos" with MBR and with no-so-legacy "Legacy BIOS".


Here is simplest partitions:

a) "Legacy BIOS boot" in BIOS. Switch off UEFI.

b) You don't need SWAP partition if you have 4GB RAM or more.

c) The end structure:
Code:

/dev/sda1   /boot   ext2      defaults,noatime   0 2
/dev/sda2   /      ext4      noatime         0 1
/dev/sda3   /home   ext4      noatime         0 2
# and you left 1 partition for swap and everything.

d) doing partitions:
fdisk -t dos /dev/sda

1)
Code:

Command (m for help):n
Command action
  e   extended
  p   primary partition (1-4)
p
Partition number (1-4): 1
First sector (64-10486533532, default 64): +128M

mkfs.ext2 -T small /dev/sda1


2)
Code:
Command (m for help):n
Command action
  e   extended
  p   primary partition (2-4)
p
Partition number (2-4): 2
First sector : +31000M

mkfs.ext4 -j /dev/sda2



3)
Code:

Command (m for help):n
Command action
  e   extended
  p   primary partition (3-4)
p
Partition number (3-4): 3
First sector (64-10486533532, default 64): +25000M

mkfs.ext4 -j -T small /dev/sda3



Kernel:
Code:
genkernel all
- not working. Error: -fstack-protector not supported. Instead use:
Code:
genkernel --menuconfig all


Kernel recompile:
Code:
genkernel --menuconfig --kernel-config=/etc/kernels/last-successful-kernel-config all

You do need 4GB+ (or swap) if you plan to compile large programs like chromium (last time I looked at it was 3GB RAM + 5GB disk), but yes, swap is not a requirement nowadays. If you have enough RAM, make a big tmpfs - I have 6GB for browser profile/portage tmp dir - this will keep your ssd in shape (or your hdd from spinning like crazy)

If you recompile the same kernel with genkernel --kernel-config=/path/to/your/old/config then genkernel will rename your old config (backup) and complain there is no config.
