Starting with FreeBSD the jail can not be started. In the ezjail config I specify: export jail_osmocom_builder_debian_flags="-l -U root" When executing ezjail the following command will be executed: /usr/sbin/jail -l -u root -i -f /var/run/jail.osmocom_builder_debian.conf -c osmocom_builder_debian Passing -l (or -u root) and -f together will generate a non comprehensive error message of the jail command: usage: jail [-dhilqv] [-J jid_file] [-u username] [-U username] -[cmr] param=value ... [command=command ...] jail [-dqv] [-f file] -[cmr] [jail] jail [-qv] [-f file] -[rR] ['*' | jail ...] jail [-dhilqv] [-J jid_file] [-u username] [-U username] [-n jailname] [-s securelevel] path hostname [ip[,...]] command ... When removing the flags the jail command fails in determing the uid/id of root inside the jail. This is to be understood as the database used in FreeBSD does not exist in linux. The only way to get it started is to remove three lines generated by /etc/rc.d/jail echo " exec.clean;" echo " exec.system_user = \"root\";" echo " exec.jail_user = \"root\";" Otherwise the command will fail with: jail: osmocom_builder_debian: getpwnam: No such file or directory jail: osmocom_builder_debian: sleep 2: failed >How-To-Repeat: Attempt to start a non FreeBSD jail. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
