Little helper to create tar balls of an executable together with its ELF shared library dependencies

Little helper to create tar balls of an executable together with its ELF shared library dependencies. This is useful for prototyping with gokrazy:
https://gokrazy.org/prototyping/

Installation:

go install github.com/gokrazy/freeze/cmd/[email protected]

Usage:

Let’s assume you want to try the upcoming Linux ksmbd feature.

On Linux, build ksmbd-tools:

$ git clone https://github.com/cifsd-team/ksmbd-tools
$ cd ksmbd-tools
$ ./autogen.sh
$ ./configure 
$ make -j8
$ freeze control/ksmbd.control

2021/10/24 15:29:33 Download freeze1373262977.tar to your gokrazy device and run:
	LD_LIBRARY_PATH=$PWD ./ld-linux-x86-64.so.2 ./ksmbd.control

Then, on your gokrazy device, e.g. via breakglass:

$ cd /tmp
$ wget http://10.0.0.76:4080/freeze1373262977.tar
$ tar xf freeze1373262977.tar 
$ cd freeze1373262977/
$ LD_LIBRARY_PATH=$PWD ./ld-linux-x86-64.so.2 ./ksmbd.control
Usage: ksmbd.control
	-s | --shutdown
	-d | --debug=all or [smb, auth, etc...]
	-c | --ksmbd-version
	-V | --version
