Hi all, This is the third fresh install of CentOS 7 1708 the last two months that won't boot after a regular "yum update" just after the fresh install has finished. I've never had this problem before, it has just worked. The installs are on OEM's that have previously run CentOS 6.9 x64. Am I missing something here? -- BW, Sorin
