3. systemd first boot

# systemd-firstboot --prompt --setup-machine-id

4. systemd Preset services

Most services are disabled when systemd is first installed. A "preset" file is provided, and may be used to enable a reasonable set of default services.

5. nano /etc/systemd/network/50-dhcp.network

[Match]
Name=enp2s0

[Network]
DHCP=yes

• systemctl restart systemd-networkd.service - end0 was up and set 192.168.48.7/24 - could ping hosts on the net, but ping GW 192.168.48.254 faied
• systemctl enable systemd-networkd.service

- reboot

6) `emerge app-admin/sudo` and `visudo` and


7) set time-zone

h2Gentoo /home/alexlai # cp -v /usr/share/zoneinfo/Asia/Taipei /etc/localtime '/usr/share/zoneinfo/Asia/Taipei' -> '/etc/localtime' h2Gentoo /home/alexlai # date Fri Oct 27 05:13:51 PM CST 2023

8) Your first time to sync the @world

$ sudo emerge --ask --update --deep --newuse @world
