GitHub对文件的大小有限制，问题在于，当移除了相关的文件之后，问题依然存在。
解决方法：
除了移除相关的文件，还要修改git的历史记录，移除相应的commit结点。
最简单的方法是使用以下命令：
git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch YOUR-FILE'
此命令会将指定的文件从push过程中过滤掉。
请谨慎使用此命令，强烈建议在使用前先备份，以防止误操作。
git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch rootfs.tar.gz'
