[Clfs-support] CLFS - Unable to login on the first bootup

Tue Jul 5 20:53:55 PDT 2011

Hi Grail

I was out for the weekend and got a chance to compare the procedures of x86
and x86_64 a bit more today. I then found:  x86_64 missed creating a
symbolic link /bin/login -> /tools/bin/login

In x86:
ln -sv /tools/bin/{bash,cat,echo,grep,login,pwd,sleep,stty} ${CLFS}/bin

But in x86_64 it was instead:
ln -sv /tools/bin/{bash,cat,echo,grep,pwd,sleep,stty} ${CLFS}/bin

Now I'm able to login and get the bash shell. Will now try out the remaining
steps and update how it went and most probably bug you guys back again when
I'm stuck :D

PS: I guess agetty takes the username and passes it onto login binary, which
is the one which asks for the password (at least what I could observe based
on the man page of login and the problem I faced)

Thanks.
