This pair of patches works to allow makepkg to sign packages inside makechrootpkg; something that while perhaps not useful for the Arch packaging toolchain itself, is immensely helpful to getting all of us unofficial packagers in the community doing both signed packages and clean builds.
The first patch adds an option to makechrootpkg that translates into --setenv on systemd-nspawn; the second passes necessary variables through sudo over to makepkg and thus to gpg.
To make it all work, call makechrootpkg (or the appropriate archbuild alias) with the following arguments: -d "$HOME/.gnupg/S.gpg-agent:/build/.gnupg/S.gpg-agent" -e "DISPLAY=$DISPLAY" -e "GPG_TTY=$(tty)"
This will pass the agent socket into the chroot, tell gpg where to tell the agent to start the pinentry, and works quite well both in X and on the terminal.
--- Patrick Burroughs (Celti) (2): allow passing --setenv to nspawn let sudo pass DISPLAY and GPG_TTY to builduser

This requires the previous patch to enable -e/--setenv to work, and allows with the appropriate flags to sign packages within the chroot. --- makechrootpkg.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
