Hello,
I have found an issue in the rootfs routine. The
rootfs-postcommands.bbclass has a funtion systemd_create_users that
reads /etc/sysusers.d/*.conf files and parses lines as 'type name id
comment'.
However, the sysusers.d manual says, those lines can be 'type name id
comment home_dir shell'. If a home directory of shell is defined, they
are considered as part of the comment, and we run incorrect commands
such as the one below :
useradd --shell /sbin/nologin --uid 0 --comment "Super User" /root
--system root
To fix that, we require a stronger parsing. Several options look
possible to me, but I am not sure which one is preferred.
1. sed with a regular expression that returns something that still needs
parsing
2. awk with a step by step script that returns something that still
needs to be parsed
3. use python and regexp module
Also I don't know if the parsing should completely check the sysusers
syntax as said in the manual (first field is [urgm], second is
alphanum_-, etc.). In my opinion it should not as this will be made by
the useradd command.
Do you think it worth to add some testing about that ? I am not sure how
to do that.
Regards,
Louis Rannou
