We have never seen anything but :0 or :1 as a virtual terminal before. A
system reboot will reset the terminal back to :0, but it will then increment
with each login. Anyone seen this before, understand why it has happened,
and/or know how to reverse the trend? This system has been running CentOS 7
for about 7 years without any significant changes.
Best,
Walt
