When using a script/wrapper to a) build packages in a clean chroot (e.g. with extra-x86_64-build), and b) install the created package, pacman's "Proceed with installation? [Y/n]" prompt terminates before user input, and no installation occurs.

Additional info:

I'm still not sure if this is a problem with systemd-nspawn, with devtools' mkarchroot script, or even with something else. Disabling systemd-nspawn by setting have_nspawn to 0 (line 344 of mkarchroot) fixes the problem.

Forum thread :-

package version(s):
>= devtools-20121003-1 (i.e. when systemd-nspawn was added to mkarchroot)
Only tested with systemd-194-4

Tested on two machines with identical results.

Steps to reproduce:

- Have systemd as PID 1
- Set up chroot (e.g. for extra-x86_64)
- Get a PKGBUILD (e.g. for devtools-20121013-1)
- Run (as root): extra-x86_64-build && pacman -U devtools-20121013-1-any.pkg.tar.xz
- Run (as normal user): sudo extra-x86_64-build && sudo pacman -U devtools-20121013-1-any.pkg.tar.xz

Note that by running the commands separately, e.g.
root@host# extra-x86_64-build
root@host# pacman -U devtools-20121013-1-any.pkg.tar.xz

The expected behaviour occurs, and the pacman prompt waits for user input.
This task depends upon
