Busybox adduser cannot create system user "no uids left"

Busybox adduser cannot create system user "no uids left"

[Samuel Stirtzel]

Hi,

with the current master/HEAD it seems impossible to create system
users with busybox.


root@overo:~# which adduser
/usr/sbin/adduser
root@overo:~# ls -la /usr/sbin/adduser
lrwxrwxrwx    1 root     root            19 Aug 29  2013
/usr/sbin/adduser -> /bin/busybox.nosuid
root@overo:~# adduser --system --ingroup lightdm lightdm
adduser: no uids left


Normal user creation works as expected.
Content of /etc/passwd:

root:x:0:0:root:/home/root:/bin/sh
daemon:x:1:1:daemon:/usr/sbin:/bin/sh
bin:x:2:2:bin:/bin:/bin/sh

polkitd:x:996:992::/etc/polkit-1:/bin/sh


Can anyone reproduce this error, or is it a known problem?

That's because CONFIG_SYSTEM_LAST_ID is set to 0 in defconfig.
I'll send out a patch to fix it.

Hi,

sorry for the late answer, yes this would be great.

All "manual" installations (e.g. make && make install && useradd ...)
are affected.
Until now I did not test any packages that use the useradd.bbclass and
are installed after do_rootfs.
I suspect these package installations (that create system users) are
also broken, but I need to test it.
