When I enter into grub menu, I get two entries :
CentOS Linux (3.10.0-514.21.1.el7.x86_64) 7 (Core) CentOS Linux (0-rescue-e1ac24cbe9f94f2caa228d77e027be8b) 7 (Core)
When I boot into the second line (the rescue one), I get a normal prompt like if I had boot into the first line. I was expecting someting like a rescue shell or something equivalent to single-user mode but it still asking me for root password, root FS is not in read only mode etc. Nothing seems different from multi-user mode.
Can someone try on its distro to see if it has the same behavior? I'm pretty new to rescue, emergency, single-user modes so I might have missed someting.
Here is my conf :
[root@centos3 ~]# uname -a Linux centos3 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux [root@centos3 ~]# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core)
