Hello Simon!

By using =E2=80=98-S /etc=3Detc=E2=80=99, you provide /etc/profile in the c=
ontainer.
Thus, if you run =E2=80=9Cbash=E2=80=9D (or =E2=80=9Cbash --login=E2=80=9D?=
) in there, /etc/profile is
automatically sourced, which solves the problem, I think.

But it=E2=80=99s not very convenient.

Perhaps we should populate the =E2=80=98Environment=E2=80=99 bit of the Doc=
ker manifest
file?  It sounds like it would greatly improve things.

WDYT?

Thanks,
