[arch-projects] [devtools] [PATCH 1/2] makechrootpkg: specify makepkg.conf with -M

[Alad Wenter]

PKGDEST and other variables can be set in /etc/makepkg.conf and local
correspondents in $HOME, with the file in /etc taking precedence.
Specifying a default makepkg.conf on the command line (similar to
makepkg) allows to change the directory where build products are moved
(move_products), without the need to modify the system configuration
in /etc/makepkg.conf or rely on sudoers policy.

Fixes FS#44827
