We know we can add some other remotes and its url after an initial git remote
add origin, and one more trick is that we can do some group aliases such as:
# <repo>/.git/config
[remote "mars"]
url = <url-mars>
fetch = +refs/heads/*:refs/remotes/origin/*
[remote "origin"]
url = <url-origin>
fetch = +refs/heads/*:refs/remotes/origin/*
[remote "all"]
url = <url-mars>
url = <url-origin>

致命的指令失誤是每個 linuxer 成長過程中必定有過的經驗, 誰也免不了.
別不信邪, 即使是 Gentoo Portage 的 official ebuild,
也曾經出現過 rm -rf /lalala 誤寫為 rm -rf / lalala ,
造成使用者更新套件後系統全毀的慘劇…

»We cannot solve our problems with the same thinking we used when we created them.
Consider a situation that you want to change some settings i.e. edit some files in VM, it’ll be nice if you don’t have to boot it up then log in to make some changes. So the question becomes how to access the file system inside the VM disk image file?
