Load Average Below the Number of CPU Cores: A common rule of thumb is to keep the load average below the number of physical CPU cores or threads available on your system. For example, on a quad-core CPU, a load average of 4 or below is generally considered good.

- First sync,
emerge --syncoremerge-webrsync
emerge --sync fetches the complete tree, while emerge-webrsync fetches a smaller, compressed snapshot, making it a faster option in some situations, but it may not provide all the files available in a full sync. The choice between the two commands depends on your specific needs and the constraints of your environment.

- Configuring the USE variable
As we said, USE flags are a core feature of Gentoo. Therefore, a good understanding of how to deal with them is needed to have a customized and healthy Gentoo system.
The USE variables can be defined system-wide or per package domain. You can read more info here:
- System-wide in [/etc/portage/make.conf](https://wiki.gentoo.org/wiki//etc/portage/make.conf#USE)
- Per package in [/etc/portage/package.use](https://wiki.gentoo.org/wiki//etc/portage/package.use)
We can see the list of USE flags that are set up in our system by running:
(chroot) livecd / # emerge --info | grep ^USE
USE="acl amd64 bzip2 cli crypt dri fortran gdbm iconv ipv6 libtirpc multilib ncurses nls nptl openmp pam pcre readline seccomp split-usr ssl systemd test-rust udev unicode xattr zlib" ABI_X86="64" ADA_TARGET="gnat_2021" APACHE2_MODULES="authn_core authz_core socache_shmcb unixd actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="karbon sheets words" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" CPU_FLAGS_X86="mmx mmxext sse sse2" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock greis isync itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf skytraq superstar2 timing tsip tripmate tnt ublox ubx" INPUT_DEVICES="libinput" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" LUA_SINGLE_TARGET="lua5-1" LUA_TARGETS="lua5-1" OFFICE_IMPLEMENTATION="libreoffice" PHP_TARGETS="php8-1" POSTGRES_TARGETS="postgres15" PYTHON_SINGLE_TARGET="python3_11" PYTHON_TARGETS="python3_11" RUBY_TARGETS="ruby31" VIDEO_CARDS="amdgpu fbdev intel nouveau radeon radeonsi vesa dummy v4l" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq proto steal rawnat logmark ipmark dhcpmac delude chaos account"
- for example
USE="acl amd64 bzip2 cli crypt dri fortran gdbm iconv ipv6 libtirpc multilib ncurses nls nptl openmp pam pcre readline seccomp split-usr ssl systemd test-rust udev unicode xattr zlib"
This USE flag information can be broken down as follows:
- USE: These flags are used to control various options and dependencies for packages. Here's a breakdown of some of the specific USE flags listed in the output:
- amd64: This flag indicates that the system architecture is 64-bit AMD.
- bzip2: This flag indicates that the Bzip2 compression library support is enabled.
- dri: Direct Rendering Infrastructure for accelerated graphics.
- fortran: Fortran language support is enabled.
- ipv6: IPv6 support is enabled.
- systemd: Systemd support is enabled.
- test-rust: This flag is likely related to Rust language testing.
- udev: Udev device manager support is enabled.
- unicode: Unicode character support is enabled.
- zlib: Zlib compression library support is enabled.
We can find a description of all USE flags in less /var/db/repos/gentoo/profiles/use.desc.
Additionally, the utility named quse from portage-utils package can tell us which package uses what USE flags.
For example, if you want to know which packages use the systemd flag we simply need to run:
quse systemd --> shows the list of packages affected by systemd.
In your case, since the USE variable is not present in your /etc/portage/make.conf file, your system is likely using the default USE flags provided by the selected profile. This is a common configuration for many Gentoo systems, as it simplifies the management of USE flags by relying on profile defaults.

- Configuring the CPU Flags
USE flags that are available for our system. We could use the advantages of some CPU instruction sets using what are called CPU flags. You can read more on the Gentoo CPU_FLAGS_X86 wiki page.
To know what optimizations we can use for our CPU, we're going to use a tool called cpuid2cpuflags:
emerge --ask app-portage/cpuid2cpuflags
# emerge app-portage/cpuid2cpuflags
(chroot) hc4Mantic / # cpuid2cpuflags
CPU_FLAGS_ARM: edsp neon thumb vfp vfpv3 vfpv4 vfp-d32 aes sha1 sha2 crc32 v4 v5 v6 v7 v8 thumb2
nano /etc/portage/make.conf
- And we add our CPU_FLAGS_X86 somewhere in the file.

- Re-compile and update @world
After setting up the USE and CPU flags, we're ready to re-compile and update all packages that we have installed in our base system before moving forward:
When you select a Gentoo profile during the installation of your Gentoo system, the profile typically includes a set of default USE flags that are already configured for you. These default USE flags are designed to be a good starting point based on the intended purpose of the profile.
emerge --ask --verbose --update --deep --newuse @worldoremerge -avuDN @world
- Allow licenses for packages
Each package in our Gentoo system defines what kind of license it uses. Setting what licenses we accept in our system is crucial to avoid problems installing free or binary redistributable packages. Also, to get installed automatically without asking us every time they get installed or updated.
You can read more about Gentoo licenses here.
Licenses acceptance is set in our /etc/portage/make.conf in the variable ACCEPT_LICENSE, like:
ACCEPT_LICENSE="-* @FREE @BINARY-REDISTRIBUTABLE"
- This line defines which licenses are acceptable and which are not. Let's break it down:
- ACCEPT_LICENSE="-*": The - symbol followed by * means that you are denying all licenses by default. In other words, you are saying that any package with an unspecified license (or a license not explicitly listed in the ACCEPT_LICENSE variable) is not acceptable.
- @FREE: This part of the line specifies that packages released under licenses that are categorized as "free" are acceptable. Free licenses generally grant you the freedom to use, modify, and distribute the software without significant restrictions.
- @BINARY-REDISTRIBUTABLE: This part of the line specifies that packages with licenses categorized as "binary redistributable" are also acceptable. These are licenses that allow you to redistribute compiled binary versions of the software.
- Timezone
We can use the tool tzselect to interactively select our country, and it will tell us what the value of /etc/timezone file should be.

- Installing external firmware
Linux kernel is an open-source project, but some hardware manufacturers don't like the idea of open-source the code of its firmware (or modules), releasing a compiled binary version of them. These binaries can't be included in the Linux kernel repository, and they are packed in a package called sys-kernel/linux-firmware.
So, before compiling the kernel, it is essential to know that some devices require additional firmware to make the system run properly. Second, these are more common than we think, from network adapters, wireless cards, graphic cards, and CPUs.
For the most common firmware requirements, we will install the sys-kernel/linux-firmware:
$ emerge --ask sys-kernel/linux-firmware `
