[yocto] Useradd: crypted passwords longer than 8 characters

[Lukasz Zemla]

What is the best way in Yocto (warrior) to add crypted password to /etc/shadow during buildtime?

Using useradd.bbclass in a standard way we may add only passwords <= 8 characters.
"-p" parameterr followed by the output of "openssl passwd -crypt pAsswOrd" works fine.

I thought that class may be cheated by providing after "-p" string returned by "openssl passwd -6 verylongpAsswOrd", but it does not work: the password in /etc/shadow file is truncated:

myuser:/D163GofCVEpMgZ.w2Ro3Z.b5S8XT1:18190:0:99999:7:::

Any suggestions?

Thank you in advance.
