In this section, you will need to choose a disk format to use for booting and partitioning -- either MBR or UEFI/GPT. If you are not familiar with the differences between these options, please review our Disk Formats page for an overview of each option and the trade-offs. Generally, it's usually safe to pick the GPT method with a BIOS Boot partition to enable legacy booting, and install UEFI.

But First...

Before doing anything to your disks, make sure you are partitioning the right one. Use the lsblk command to view a list of all block devices on your system, as well as partitions on these block devices:

root # spaceball-1 ~ # lsblk -o model,name,size,label,partlabel
MODEL            NAME     SIZE LABEL                    PARTLABEL
ST31000340AS     sda    931.5G                          
                 └─sda1 931.5G HOME                     
PNY CS900 120GB  sdb    111.8G                          
                 ├─sdb1     1M                          BIOS Boot
                 ├─sdb2   256M BOOTF                    BOOTF
                 └─sdb3 111.6G FUNTOOL                  FUNTOOL
USB 2.0 FD       sdc      3.8G Ubuntu 20.04.1 LTS amd64 
                 ├─sdc1   2.6G Ubuntu 20.04.1 LTS amd64 
                 └─sdc2   3.9M                          
Portable         sdd      1.8T                          
                 └─sdd1   1.8T Seagate Portable Drive

Now that we know what drive we're targeting to install, we will set udev rules to alias the drive as /dev/funtoo, and partitions as /dev/funtoo1 /dev/funtoo2 etc. undead usb uses the second official partitioning scheme, which is swapless, the official install guide uses the first official partitioning scheme with a swap partition to avoid the performance hit from mounting swap by file.

The first rule of funtoo is funtoo rules.

• ide drive #3 example:

root # echo 'KERNEL=="hdd*", SYMLINK+="funtoo%n"' > /etc/udev/rules.d/01-funtoo.rules

• sata drive #2 example:

root # echo 'KERNEL=="sdc*", SYMLINK+="funtoo%n"' > /etc/udev/rules.d/01-funtoo.rules

nvme & mmc require two rules, 1 for the drive location, and the other for the drive location, and partition number.

• nvme nvme drive 1 example:

root # echo 'KERNEL=="nvme1n1", SYMLINK+="funtoo"' > /etc/udev/rules.d/01-funtoo.rules
root # echo 'KERNEL=="nvme1n1p*", SYMLINK+="funtoo%n"' >> /etc/udev/rules.d/01-funtoo.rules

• mmc drive 0 example:

root # echo 'KERNEL=="mmcblk0", SYMLINK+="funtoo"' > /etc/udev/rules.d/01-funtoo.rules
root # echo 'KERNEL=="mmcblk0p*", SYMLINK+="funtoo%n"' >> /etc/udev/rules.d/01-funtoo.rules

root # udevadm control --reload-rules && udevadm trigger

I need to mount the 1.8tb usb drive today, notice I leave the star for /dev/funtoo2 to point to /dev/sdd2

• sata drive #2 example modified to load /dev/sdd:

root # echo 'KERNEL=="sdd*", SYMLINK+="funtoo%n"' > /etc/udev/rules.d/01-funtoo.rules
root # udevadm control --reload-rules && udevadm trigger

Now running ls -al /dev/funtoo will point to my drive that I am targeting to install. /dev/funtoo -> sdd

• you can think of /dev/funtoo as /dev/sdX install instructions, but were mounting our drive were installing to /dev/sdX so everything on the install is copy paste, and safely pointed away from drives you might care about.
