[CentOS] yum update info output

Hi all,

when I check for updates with yum, it gives me a list of packages, with some additional info, e.g.

  --> systemd-sysv-219-42.el7_4.1.x86_64 from @updates removed (updateinfo)
  --> systemd-sysv-219-42.el7_4.4.x86_64 from updates removed (updateinfo)


yum info will tell me that I have 4.1 of this package installed, and that 4.4 is available - from the 
repo updates.

What is the meaning of the "@" - it marks the older package?

And why are all packages always "removed"?

It would seem that both mentioned packages are still available...

Regards,
Thomas
