Comment # 20 on bug 1013206 from Ancor Gonzalez Sosa

The main problem here is that the YaST code is conceived to work only on the
inst-sys. I mean, it uses the so-called installation extensions to load
dict-full dynamically. See this code:

https://github.com/yast/yast-users/blob/29d0c407f6d15a89da7cfa856c9f9e1c65dbeef0/src/modules/UsersSimple.pm#L973

But that results in the following errors in the logs:

[Ruby] modules/InstExtensionImage.rb:386 Calling: extend
'cracklib-dict-full.rpm'
[bash] ShellCommand.cc(shellcommand):78 sh: extend: command not found
[Ruby] modules/InstExtensionImage.rb:388 Returned: $["exit":127, "stderr":"sh:
extend: command not found\n", "stdout":""]
[Ruby] modules/InstExtensionImage.rb:392 'extend' failed!
[Ruby] users/local_password.rb:97 loading cracklib failed, not used for pw
check[Ruby] modules/InstExtensionImage.rb:418 Package cracklib-dict-full.rpm
wasn't integrated

We would need either to adapt YaST to recognize the situation and not try to
use the installer extensions (i.e. using the 'extend' command) or to provide
'extend' in the live system with a different behavior when compared to the
inst-sys (e.g. checking if something is there, instead of trying to load it
temporarily.
