Re: boot problem after updating dropbear [solved -- MANUAL initrd works required]

Hi,

Okay, it turns out that the only files that were missing were ones that
I had in the /etc/initramfs-tools/root/ directory.


The only files in the faulty initrd image were from the
/etc/initramfs-tools/root/.ssh/ directory, so missing .profile and other
required files.


I modified the initrd to include those missing files and everything is
functional again.

 - extract initrd
 - add files
 - rebuild initrd

 - replace /boot/initrd file with my new one.

So, it seems that "update-initramfs -u -k all" only missed those extra
custom files placed in the /etc/initramfs-tools/root/ directory.

There was not anything particularly special in the .profile, except for
the useful aliases -- however, those aliases /may/ have helped the /init
script find required binaries to boot properly.

I cannot seem to find any reason why those files were included properly
before, but not now (without manual intervention).

Here's the .profile fwiw:

# cat initrd-wrk--20160926b/root/.profile
# ~/.profile: executed by Bourne-compatible login shells.

alias l='ls -alrt'

# dropbear aliases
