Are you denying that this is a bug? Are you denying that there=E2=80=99s a usability issue at hand? To me, what =E5=AE=8B=E6=96=87=E6=AD=A6 reported at the beginning of this t= hread is a usability issue. We=E2=80=99ve hacked around it so far, but we know there = are cases where the hacks aren=E2=80=99t enough. We could declare it as =E2=80=9Cwon=E2=80=99t fix=E2=80=9D, but I=E2=80=99m= not comfortable with that. >>> For example, when I do: >>> >>> GUIX_IGNORE_SYSTEM_PROFILE_ENV=3D1 guix system build my-config.scm >>> >>> the "etc/profile" of the built system will not contain those 'eval ...' >>> lines.

Please let=E2=80=99s also consider the bug at hand. The solution I came up with might be inadequate. Then we need to come up with an alternate proposal, or to resign and mark it as =E2=80=9Cwontfix= .=E2=80=9D What would you suggest? Thanks, Ludo=E2=80=99.
