This issue deserves a much more article, in fact, a straightforward tip:
You may be able to continue a normal boot only by typing “exit” and hitting enter in the “Dracut” console.
Most of the time this Dracut console entering is caused because the system administrator of the server/machine added, replaced or deleted a RAID or similar device and forgot to update the configuration (grub2 probably). And in most of these cases, the raid is not critical for machine normal boot from the root partition, but it may be critical for the services lately. Booting in normal mode, even without some devices, is the main goal because under the normal mode it easier to repair the system.
Check out the two articles on the topic (especially the first one):
It’s worth noting that if you executed some commands in the console and/or mounted devices to test they are with healthy file system or for whatever reason you did it, the boot process may not continue after typeing exit and probablly a reboot is required. The server will go once more in this mode and then just typing will work.
Apparently, the team behind the CentOS 8 decided to split the rsync functionality to two packages – one for the client-side and for the server-side, despite the binary rsync is only one and offers the client-size and server-side.
So there two packages in CentOS 8:
rsync – provides the client-side and server-side as usual
rsync-daemon – provides configuration example file and the systemd to start it as a service.
So if you wonder where is your rsync service after installing the rsync package under CentOS 8 you must install additional package “rsync-daemon”.
Of course, you may just create anywhere “rsyncd.conf” (the best place for the configuration file is in /etc, but could be placed anywhere with “–config=PATH/FILE” option) file and start the daemon as usual with “–daemon” option included to have the rsync server-side up and running.
rsync --daemon --config=/etc/rsyncd.conf
Just create yourself the configuration “/etc/rsyncd.conf” file.
Install the rsync program – the client and the daemon
dnf install rsync
Install the configuration and systemd files
dnf install rsync-daemon
rsync and rsync-daemon files
The files included in the two packages:
[root@srv ~]# dnf repoquery -l rsync-daemon

This article is for those of you who do not want to install a whole new operating system only to discover some technical details about the default installation like disk layout, packages included, software versions and so on. Here we are going to review in several sections what is like to have a default installation of CentOS 8.0.
Despite the kernel is 4.18 it detects successfully the new RYZEN/Threadripper AMD and the system is stable (we booted in UEFI mode).
The CentOS 8.0 (8.0.1950) you can have
linux kernel – 4.18.0 (4.18.0-80.7.1.el8_0.x86_64)
Graphical User Interface
Xorg X server – 1.20.3
GNOME (the GUI) – 3.28.2
K Desktop Environment – NO, it’s depricated and not included in the release.
Minimal net install is useful when a dedicated server is installed from a IPMI KVM or Dell iDRAC, HP iLO, IBM IMM or where the initial client side download of files need to be minimal.
For amd64 CentOS 8 BaseOS the net install bootable media is located here (now the current latest release is 8.0.1950, but you can check the last directory with 8. for the time you follow this howto):
