Pipeline to import new version of exim4 from Bookworm fails during prepare-build-env

Steps to reproduce

Trigger a new pipeline on the debian/bookworm branch of pkg/exim4:

• https://gitlab.apertis.org/pkg/exim4/pipelines/new?ref=debian/bookworm

Expected result

The new version from bookworm is imported and a MR is created.

Actual result

The pipeline fails at prepare-build-env with the following issue:

exec /usr/bin/dumb-init: argument list too long

See: https://gitlab.apertis.org/pkg/exim4/-/jobs/2562253

Reproducibility

How often the issue is hit when repeating the test and changing nothing (same device, same image, etc.)?

Put the ✅ in the most appropriate entry:

1. ✅ always
2. often, but not always
3. rarely

Impact of bug

We cannot import the new versions of exim4 using the pipeline that means we are behind Bookworm for exim4.

Root cause

TBD

Outcomes

• pkg/apertis-dev-tools!64 (merged)
