Hi,

is there anything speaking against making such updates more
comfortable?

Since the login shell is affected, it's not a simple chicken-and-egg
problem an Arch user usually expects to happen.

Providing a transition package including libncursesw.so.5 might cause
to much work, but why not at least mentioning it by the news on
https://www.archlinux.org/ ?

It seemingly wasn't a serious issue for the OP and it neither hits me
between the eyes, however, a user might have a bad day and doesn't
notice it, especially if it's not mentioned by the news.

Btw. thank you Damjan for the heads up :).

My workaround was to mv -i the libs [1]. Btw. packages from AUR are
affected too.

2 cents,
Ralf
