Solution:

apk add linux-headers

<7> Clean unneed packages on opensuse

# add this alias to '/root/.bashrc' or '/root/.zshrc'
alias clean="zypper packages --unneeded | awk -F'|' 'NR==0 || NR==1 || NR==2 || NR==3 || NR==4 {next} {print \$3}' | grep -v Name | xargs zypper remove --clean-deps"

<8> Colorful git-diff on Alpine linux

apk add git-diff-highlight
# and then, re-login

<9> MUSL platform: "rustc: Dynamic loading not supported"

disable the default feature of 'static link'

# ~/.bashrc or ~/.zshrc
export RUSTFLAGS="-C target-feature=-crt-static"

<10> Allow setting weak password

# vi /etc/security/passwdqc.conf
enforce=none

<11> Docker modulers on gentoo

# `/etc/local.d/modprobe.start`,
# auto-generated as `gentoo-local-modprobe.service`

modprobe tun
modprobe veth

modprobe br_netfilter
modprobe iptable_filter

modprobe xt_nat

modprobe nf_conntrack
