Standalone pacman.exe usage against different root: "failed to execute correctly" during post_* scripts

I'm bootstrapping a little MSYS2-lite for a Windows Firefox developer environment.

As part of this, I'm essentially running <msys2>/usr/bin/pacman.exe -Sy --root <target> <list-of-packages ...> However, I'm seeing errors when I do this:

error: command (/usr/bin/bash /usr/bin/bash -c . /tmp/alpm_EZ35j1/.INSTALL; post_install 4.18.0-1 ) failed to execute correctly
:: Running post-transaction hooks...
(1/1) Updating the info directory file...
error: command (/usr/bin/sh /usr/bin/sh -c while read -r f; do install-info "$f" /usr/share/info/dir 2> /dev/null; done ) failed to execute correctly

Note that this only happens when running pacman.exe directly from the Command Prompt, and not when running it from an MSYS2 context.

To reproduce:

Do the following from the Command Prompt. Note that this assumes that MSYS2 is installed to C:\msys64

mkdir msys2-test\var\lib\pacman msys2-test\var\log msys2-test\tmp
cd msys2-test
C:\msys64\usr\bin\pacman.exe -Sy --root . msys2-runtime bash
C:\msys64\usr\bin\pacman.exe -Sy --root . libtasn1

Notes

While creating this bug report, I was suddenly no longer able to access mirror.msys2.org. I'm guessing that it's either because it just went down, or I'm being rate-limited. Since the packages were already cached, it doesn't appear to be affecting the bug in question
I wasn't able to reproduce this outside of pacman, because /tmp/alpm_<random>/ was removed before I could copy it. If you have tips for digging in further, I'd appreciate it :)

Alexpux / MSYS2-pacman

Standalone pacman.exe usage against different root: "failed to execute correctly" during post_* scripts #64
