Subject: struggling with apk in unattended session

Hi,

I=E2=80=99m trying to run apk command in an embedded system under no =
end-user
console/ssh interaction.
The set of scripts running the apk command works great when launched
from ssh session (produces output and log), or for instance, if it is
gated by an acpid input device (thus under root)
However, when launched by another process ( owned by user =E2=80=9Cjoe=E2=80=
=9D, who
has sudo rights on script), apk command seems to block: other preceding
commands do produce expected results and logs, but it stumbles on apk.

Are there any special consideration to take care about with apk in such
scenario?
Thanks for any tip!

Some code snippets to explain:

Result: stuff1 & stuff 3 are performed (so setup-mystuff entry passes
the sudo test!), but apk, stuff4 (and stuff2) never happen, and no
trace appear on /tmp/update.log nor /var/log/messages

cat /usr/local/bin/update
#!/bin/sh
# do stuff1 here
./setup-mystuff > /tmp/update.log 2>&1
# do stuff2 here

cat /tmp/setup-mystuff
#!/bin/sh
! [ $(id -u) =3D 0 ] && { echo >&2 "Please run as root"; exit 1; }
# do stuff3 here
apk add <some_package>
# do stuff4 here

sudo visudo -f /etc/sudoers.d/010_joe-nopasswd
