Comment 8 for bug 1833193

> I just tested it on Eoan, using systemd 242-6, and the valid__lft and preferred_lft did indeed change to 'forever'.

well that's interesting...I tested with the latest upstream systemd code and i *was* able to reproduce the problem...maybe something reverted the fix since 242. Unless, of course, I messed up my test :-) I'll backport the fix for that and see if it fixes bionic, then retest the latest upstream to make sure it hasn't reverted.

> The discussion in the GitHub issue was rather interesting as well. I kind of "agree" that this is a strange thing to do, but I don't think that should be any of systemd's business..

yes, I agree, and it is an entertaining discussion on what systemd should prevent users from doing ;)
