For example, aur/caddy-full-bin depends on systemd>=229 but I am using tredaelli-systemd/systemd 227-1 because I'm stuck on an old kernel on openvz. I have the [tredaelli-systemd] repo first in my /etc/pacman.conf. sudo pacman -Syu will not automatically upgrade me from tredaelli-systemd/systemd-227-1 to core/systemd-231-3. But if I do pacaur -S caddy-full-bin, it will upgrade without any opportunity to decline:

Even if I add systemd to IgnorePkg, pacaur will bypass the extra prompt immediately:

Using makepkg directly does try to upgrade to systemd-231-3 as well, which sucks, but I at least get the chance to decline it:

% makepkg -si

Or with IgnorePkg:

% makepkg -si              
==> Making package: caddy-full-bin 0.9.3-8 (Wed Oct  5 19:17:09 UTC 2016)

I understand if you don't care to try to enforce the /etc/pacman.conf repository order masking which not even makepkg obeys, but I think pacaur should at least not bypass IgnorePkg for you automatically.

My /etc/xdg/pacaur is default/all comments and I'm using pacaur 4.6.10.

What's displayed on the main prompt when running pacaur -S caddy-full-bin?

at this point it just stalls, most likely because some systemd-related thing has already crashed due to being incompatible with the openvz kernel.

Or maybe it's stalling waiting for a password input again, I just noticed the second [sudo] password for vith: in the middle of the last segment.

But yeah anything after systemd gets upgraded I'd just consider undefined behavior at this point.

I see. There is no version check done on binary dependencies, since pacaur assumes the system is not in a partial upgrade state (which your system effectively is). Since the older systemd is found as installed, no further check are processed either. This only concerns the main prompt display, binary installation is otherwise entirely handled by makepkg.

Installing aur/caddy-full-bin correctly shouldn't prevent the new systemd to be installed, but ideally the ignore prompt would be displayed on the main prompt, along with the new systemd dependency.

I am not sure if the work involved is worth it though. After all, this is a very specific situation that shouldn't last long. I'll have a look, but no promise.
