甲骨文云 - ARM机 - 安装 Debian 12 bookworm ARM64
需求；甲骨文云中的ARM机，有提供免费的 Canonical-Ubuntu-22.04-Minimal-aarch64 系统镜像。如果想使用 Debian 12，能不能安装呢？
实践；能。用 Debian 提供的网络安装文件，能完成。如在已有的 Ubuntu 中，使用 kexec 来启动到带远程 ssh 的 Debian 安装界面。举例：kexec --command-line="priority=critical mirror/http/hostname=ftp.us.debian.org interface=auto language=en country=US locale=en_US.UTF-8 keymap=us modules=network-console network-console/password=hellodebian network-console/password-again=hellodebian DEBIAN_FRONTEND=text" --initrd=initrd.gz linux
如果是静态IP的，或许是：
kexec --command-line="priority=critical mirror/http/hostname=ftp.cn.debian.org interface=auto netcfg/disable_autoconfig=true netcfg/get_ipaddress=192.168.1.61 netcfg/get_netmask=255.255.255.0 netcfg/get_gateway=192.168.1.1 netcfg/get_nameservers=8.8.8.8 language=en country=US locale=en_US.UTF-8 keymap=us modules=network-console network-console/password=hellodebian network-console/password-again=hellodebian8 DEBIAN_FRONTEND=text" --initrd=initrd.gz linux
另有 ISPSystem中Debian 11 和 Debian 11 netinstall 包中 metainfo.xml 的内核参数实例，可对比：
<kernelcommand>url=($OSINSTALLINFO_HTTPv4) language=en debian-installer/country=RU locale=en_US keyboard-configuration/xkb-keymap=us console-keymaps-at/keymap=us interface=auto netcfg/disable_dhcp=true netcfg/disable_autoconfig=true netcfg/use_autoconfig=false ipv6.autoconf=0 netcfg/get_ipaddress=($IPv4) netcfg/get_netmask=($NETMASKv4) netcfg/get_gateway=($GATEWAYv4) netcfg/get_nameservers=($NAMESERVERv4) hostname=($HOSTNAME) domain=($HOSTNAME) netcfg/hostname=($HOSTNAME) net.ifnames=0 netcfg/link_wait_timeout=30</kernelcommand>
<kernelcommand>url=($OSINSTALLINFO_HTTPv4) language=en debian-installer/country=RU locale=en_US keyboard-configuration/xkb-keymap=us console-keymaps-at/keymap=us interface=auto netcfg/disable_dhcp=true netcfg/get_ipaddress=($IPv4) netcfg/get_netmask=($NETMASKv4) netcfg/get_gateway=($GATEWAYv4) netcfg/get_nameservers=($NAMESERVERv4) hostname=($HOSTNAME) domain=($HOSTNAME) netcfg/hostname=($HOSTNAME) netcfg/link_wait_timeout=30</kernelcommand>
