Hi all
I'm facing an issue while running dovecot inside a singularity (https://sylabs.io/singularity/) container
dovecot version is 2.3.4.1 (configuration below) running on debian buster, inside a container made with singularity version 3.4.2
unfortunately, when I try to start dovecot, it gives: Singularity test.sif:~> cat /var/log/mail.log Dec 30 17:23:38 testnode dovecot: master: Dovecot v2.3.4.1 (f79e8e7e4) starting up for imap, lmtp, sieve, pop3, submission (core dumps disabled) Dec 30 17:23:38 testnode dovecot: anvil: Fatal: We couldn't drop root privileges Dec 30 17:23:38 testnode dovecot: master: Error: service(anvil): command startup failed, throttling for 2 secs
the same happens on singularity containers based on debian bullseye or alpine linux 3.9.2
many thanks! nzasch
