Re: late_command to get user entered password
> Is the password blanked out to prevent someone printing it out?
Yes. The late_command part is executed in finish-install.d/07preseed,
while the user setup is in finish-install.d/06user-setup, and the
passwords are cleared just after user. To get access to the user
password, you would have to either put a hook in pre-pkgsel.d or
earlier in finish-install.d. Using late_command is not going to work.
