linux克隆后重新封装,克隆后立即在OSX上修改Linux内核源代码
當我在OS X上克隆
Linux源代碼時,它們會立即被更改,并且git reset –hard不會將內容恢復.這是一個完整的會議：
$git clone git://github.com/torvalds/linux.git
$cd linux
$git status
On branch master
Your branch is up-to-date with 'origin/master'.
Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)

modified: net/netfilter/xt_TCPMSS.c
no changes added to commit (use "git add" and/or "git commit -a")
我們可以看到,克隆后文件立即發生了變化.甚至不是他們的元數據,而是內容：
git diff include/uapi/linux/netfilter_ipv6/ip6t_HL.h
index ebd8ead..6e76dbc 100644

到底是怎么回事？為什么在克隆后立即修改文件？
總結
