If you have one or more configurations a long time in operation, after so many upgrades one of the aspects you tend to forget is which version of O.S. is applicable.
Through a command at Putty's CLI ist is easy to find
Code: Select all
cat /etc/os-release
Recent experience triggers to ease the way to check.
In category 'nice-to-have', would it be possible to add in that upper left corner a similar line indicating which O.S. is 'under the hood'?
If in the alert-for-upgrade a mandatory relation with an O.S. would be mentioned, then it is quite easy to compare.

obviously that latter function would be next level of nice-to-have ....
