I have been using the Yocto 2.3.3 version.
It is mainly unchanged useradd_example. The according line is
# USERADD_PARAM specifies command line options to pass to the
# useradd command. Multiple users can be created by separating
# the commands with a semicolon. Here we'll create two users,
# user1 and user2:
USERADD_PARAM_${PN} = "-u 1200 -d /home/user -r -s /bin/sh -P '' user; -u 1201
-d /home/guest -r -s /bin/sh -P '' guest"
and in the image-recipe I added:
EXTRA_IMAGE_FEATURES += "read-only-rootfs"
CORE_IMAGE_EXTRA_INSTALL += "useradd-example"
inherit extrausers
EXTRA_USERS_PARAMS = "usermod -P root root; usermod -P user user; usermod -P
guest guest"
...
But I also tried to leave the usermod command and add the password here:
USERADD_PARAM_${PN} = "-u 1200 -d /home/user -r -s /bin/sh -P 'user' user; -u
1201 -d /home/guest -r -s /bin/sh -P 'guest' guest"
...
The "read-only-rootfs" seems to make the difference, but I don't understand
why.

[yocto] passwd fails for other users than root
I have 2 extra users (added with useradd_example.bb). Login works for all 3 parties. While login works, passwd (to change it) doesn't work for the extra users. They will asked for the old one - which fails. Root is not to be asked for old password. That's way root can change password for all. The strange issue is, that after root changes password for users, they can do it by themselves. Seems that login and passwd use different algos!?!? Same password, but different hashes: before (created by yocto) user:$6$bk.Az/8KVV$v3TyAlroQeBZA3faJ.DxCVsCUBZaSAvB4FkuNkLDdsIchrmz6OnUGRnQI5BOgOjQ3mvj9QL3US6Amf2VWr0.j/:17598:0:9:7::: behind (changed by root): user:$1$d3Uo1g82$Il2kYQj8qadzQvkwUU4Ia.:17598:0:9:7::: Edit: After a few further test I found that this has an effect: I used EXTRA_IMAGE_FEATURES += "read-only-rootfs" to create a read-only-rootf (by default). But of course I did make the partition writeable before attempting to change the password. But for some strange reasons this is not same.
