boot2docker: acpid, libiconv and ntpclient for x86_64

(1/2) > >>

nuxlli:
Hello everyone,

I think most people here already know the http://docker.com, and perhaps a good amount of people also have knowledge of a parallel project that allows the use of Docker in Mac OS X through a virtual machine called https://github.com/boot2docker/boot2docker.

The boot2docker project currently uses a custom x86_64 kernel (having aufs support being the main motivation for this), and a distribution using the x86 packages of Tiny Core Linux.

All this is mounted on a bootable iso on VirtualBox, and here lies a problem and my question. For a full support of VirtualBox resources, VBoxGuest Additions must be installed. But despite the x86_64 kernel from boot2docker, the user space is x86, thus making it impossible to install all the features of VBoxGuest Additions. (more information https://github.com/boot2docker/boot2docker/blob/master/Dockerfile#L131-L151)

Today, boot2docker is mounted with a user space in x86 because of the lack of three extensions on Tiny Core Linux x86_64: acpid, libiconv and ntpclient.

In my research I found that the "source" for the libiconv generation is in x86 http://www.tinycorelinux.net/5.x/x86/tcz/src/libiconv/. I believe that porting in this case is simpler. But the acpid and libiconv packages do not offer an extension framework anywhere (at least that I could find).

How could I proceed to have these three extensions on the x86_64 platform? And in the event that I even have to port them for x86_64 what would be the steps to do it (besides probable adjustments in the source code of these extensions)?

Juanito:
There is no need for libiconv as the iconv functions are supplied by glibc (for some time now).

Please feel free to submit extensions for acpid and ntpclient - the wiki explains how to do this.

Searched for the password for user tc  in boot2docker, had to change it before ssh was possible.
What is the default password for user tc ?


--- Code: (bash) ---login as: tc
tc@192.168.8.157's password:
Access denied
tc@192.168.8.157's password:
                        ##         .

Have you tried some bootcodes like secure or superuser

There is no default password.
Set it and add the following to /opt/.filetool.lst.  Then do a backup

etc/passwd
etc/shadow
