During testing Oracle Linux 8 vs 7 I discovered that console is behaving differently. Oracle Linux 8 has different md5 of terminfo entry for "linux' terminal/console compared to OL7 but even if the same terminal escape codes are not changed, they behave differently.
For example bold text, terminfo entry unchanged, works on 7, ignored on 8. Tested on UEK kernels on both versions.
echo -e '\E[1mbold'
Also color palette is different, in 8 it is more dark, harder to read.
