$ docker run --rm -it alpine:3.20 sh

/ # wget https://github.com/vulsio/gost/archive/refs/heads/MaineK00n/go-git-v5.tar.gz
/ # tar -xvf go-git-v5.tar.gz
/ # cd gost-MaineK00n-go-git-v5/
/gost-MaineK00n-go-git-v5 # git
sh: git: not found
/gost-MaineK00n-go-git-v5 # make build

// first fetch: clone to ~/.cache/gost/vuln-list-redhat
/gost-MaineK00n-go-git-v5 # ./gost fetch redhat

// replace ~/.cache/gost/vuln-list-redhat with the outdated commit 
/gost-MaineK00n-go-git-v5 # cd ~/.cache/gost/vuln-list-redhat
~/.cache/gost/vuln-list-redhat # apk add --no-cache git
~/.cache/gost/vuln-list-redhat # git reset --hard 2be42430931ed1fb7c0ef4af98b04e91a3bf05d5
~/.cache/gost/vuln-list-redhat # apk del git
~/.cache/gost/vuln-list-redhat # cd /gost-MaineK00n-go-git-v5/

// Second and subsequent fetches: pull ~/.cache/gost/vuln-list-redhat
/gost-MaineK00n-go-git-v5 # ./gost fetch redhat

// pull success: check ~/.cache/gost/vuln-list-redhat commit hash

~/.cache/gost/vuln-list-redhat # apk add --no-cache git
