 Hi Francois,

  i'm impressed :)

it's part of TAR.bz2 ?

Are you using "root=/dev/ram0 init=/yourscript" or
"root=/dev/rd/0 init=/linuxrc" and then call you script ?

> * Oleg: how do you do, here? Do you use pivot_root with busybox's init?

i have moved "standard" /linuxrc to /linuxrc.old (it's hardlinked)
and put the shell script /linuxrc as i have posted yesterday.

I have removed my password hash before doing TAR :))
Probably pam config is overzealous and rejects the empty password.
Edit the /etc/passwd file before copying the archive contents
to CF. I hate default passwords!!!


PS. Think about day/year problem. Generally i like the year 1970,
       but 1-Jan-1970 is not great for normal users.
