[Buildroot] [Bug 7976] New: mkuser script fails with: user already exists with group nogroup

           Summary: mkuser script fails with: user already exists with
                    group nogroup
           Product: buildroot
           Version: 2015.02
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: minor
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: tommygunsster at gmail.com
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


The file:

buildroot-2015.02/support/scripts/mkusers 

Lines: 170-173:
    # check the user does not already exist in another group
    if [ -n "${_ugroup}" -a "${_ugroup}" != "${group}" ]; then
        fail "user already exists with group '${_ugroup}'\n"
    fi

Issue causes a total failure to build if the user exists with the group
already.  This shouldn't happen as it actually has less work to do right?

My work around was to comment the fail line and all seems to have continued to
work properly.

I don't know what impacts this has but as it's not failing to a real "problem"
and the mkusers script is new from what I can find, I doubt there will be any
major issues.

Enhance error messages

Hello!

The only package we have that wants to add a user with group 'nogroup' is
the mysql package, and it builds just fine here.

Do you have a custom users table? Do you have a local package that wants
to add another user with group 'nogroup'?

In any case, care to apply the attached patch and report on the new error
message, please?  (note: this patch only expands the error message, and
does not attempt to provide a fix, since I can't reproduce).

Regards,
Yann E. MORIN.

I'm not seeing anything that has the nogroup that I'm installing.  I am not
installing the mysql package though.

I do have some customization's to add some of the packages we need for the
initrd file.

Weirdly enough, i've uncommented the thing and deleted the rootfs.ext file(s)
and i'm no longer able to replicate this either.

I'll do a make clean and have it run though the entire build process and upload
the log I'm generating for this.  Hopefully we'll see the problem again.

Hello,

Do not forget to apply the patch I attached, so that you can see
more details about the failure if it happens again; this will be
extra useful to help debug the issue.

Thanks!

Yann E. MORIN.

As requested, the information of this log shows the error.  It looks like it's
coming from sshd

So while the patch is great to lead us to find the cause of the problem (in our
case it looks like it's the openssh package I have building with it) is there
anything I should look into further to help troubleshoot why this, seemingly,
small issue is occurring and the first place?

Is there also anything wrong with commenting the fail part of this so the
rootfs file can actually be built?

Tom,

Could you attach your .config pleae, so I can try to reproduce here?

And yes, this check is here on purpose: we do not want two packages
to try to install the same user with different groups. For example,
the following is clearly wrong:

    define FOO_USERS
        foo_u - foo_g - * - - -
    endef

    define BAR_USERS
        foo_u - bar_g - * - - -
    endef

because the user 'foo_u' can have only one main group. And we want to
catch this.

Regards,
Yann E. MORIN.

There's a few things have to be taken into consideration for this to work.

First, you need the structure laid out for the customizations we have.

Here's a breakdown of what I need to do.

I build on debian 7.8 x86_64 for now:

Download the structure we need from:

http://sourceforge.net/p/freeghost/code/HEAD/tree/trunk/src/buildroot/

Copy the files inside to your buildroot's extracted folder.

Copy the fog.buildroot.config.64 to .config

Then try building.

This is the simplest I can tell you for right now.  Hopefully it's helpful
enough and if you need help I'm right here.

Tom,

OK, I fond your issue.

In your Buildroot tree, you already have an sshd user in your passwd
file, see:
   
http://sourceforge.net/p/freeghost/code/HEAD/tree/trunk/src/buildroot/system/skeleton/etc/passwd

And this sshd user is part of group 99, which is 'nobody'.

This is breakage on your side.

Regards,
Yann E. MORIN.

I'm very sorry to have wasted your time then.  I should've known to look there.

Thank you very much for the assistance at any rate.
