bug#34914: ‘guix pack -f squashfs’ should create an empty /home

[Ludovic Courtès]

Hello Guix,

Once you’ve fixed <https://issues.guix.info/issue/34913>, the images
that ‘guix pack’ creates lack /home, and Singularity refuses to go
further without an empty /home because it want to mount your home
directory there but doesn’t dare to create it:

--8<---------------cut here---------------start------------->8---
$ singularity exec hwloc.sqsh 
/gnu/store/1s118hqbap2kbblpxm7nlnzqk2dskm4y-bash-static-4.4.23/bin/bash
WARNING: Non existent bind point (directory) in container: '/scratch'
WARNING: Non existent bind point (file) in container: '/etc/localtime'
WARNING: Non existent bind point (file) in container: '/etc/hosts'
ERROR  : Base home directory does not exist within the container: /home
ABORT  : Retval = 255
$ singularity --version
2.5.1-dist
--8<---------------cut here---------------end--------------->8---

I guess we’ll just have to create it.

Ludo’.
