Something like busybox in pure Go

gobox's Issues

a similar project

Hi Surma,

I have made a similar project recently called 'someutils' - https://github.com/laher/someutils - having initially seen your project, amongst others.

So, thanks for the inspiration I took from your code - I've linked you on my README because I got good ideas from you.

So, this isn't really an issue but just a heads-up & thanks.

Also, your project came up in the someutils discussion on golang-nuts aswell:
https://groups.google.com/forum/#!topic/golang-nuts/hr6Nnv20_L8

Cheers

go gettable?

would you like to consider making gobox go gettable?

not works on go1

Hello. I'm interesting on this project, but it not works in go1 release.
Can You upgrade code to ability to go get cmd/gobox ?

After that i can add dpkg reader/installer and ar reader

Not able to chroot into gobox

The default list of applets don't output a static binary, and are not able to be chrooted into using only /bin/gobox and symlinks created with -install

And the gobox -install . command installs correctly if not using a chroot, but it is not a relative path (such as the example file tree below) and therefore links to the pre-chroot path of gobox.

Is there a way to output a static binary with networking features? 😄

A quick ldd returns the following dependencies:

bash-4.3$ ldd /git/gopath/bin/gobox 
        linux-vdso.so.1 (0x00007ffe14764000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fa94151a000)
        libc.so.6 => /lib64/libc.so.6 (0x00007fa941151000)
        /lib64/ld-linux-x86-64.so.2 (0x000055e35e78f000)

I am using go version go1.6.2 linux/amd64

Here is the filesystem that is able to be chrooted into, after removing the network related applets (telnetd,httpd,wget) and manually creating the correct symbolic links:

.
└── bin
    ├── bash -> sh
    ├── cat -> gobox
    ├── echo -> gobox
    ├── gobox
    ├── grep -> gobox

Here is the size difference in case you were curious:

-rwxr-xr-x 1 aerth root  8.6M May 24 00:48 gobox-net

and ldd difference:

bash-4.3$ ldd gobox-nonet
        not a dynamic executable
