Subject: Support building image without root.
Package: live-build
Version: 5.0~a8-1
Severity: normal
Tags: upstream, patch

Dear Maintainer,

At the momemt I build my live build images inside a privileged docker container with Gitlab CI Multirunner.
I have attached a volume (/cache), and before I start "lb build" I symlink it.
The problem is cache.sh think it the same device, so it try to "hard link" copy, which of course don't work. (
Invalid cross-device link).
The problem seems to be that stat without a last slash, don't follow the symlink, but only check there the link is stored.

See for you self.
[kristian@arch-hp-laptop ~]$ mkdir test
[kristian@arch-hp-laptop ~]$ stat --printf '%d\n' test
2051
[kristian@arch-hp-laptop ~]$ ln -s /tmp symlink
[kristian@arch-hp-laptop ~]$ stat --printf '%d\n' /tmp
33
[kristian@arch-hp-laptop ~]$ stat --printf '%d\n' symlink
2051
[kristian@arch-hp-laptop ~]$ stat --printf '%d\n' symlink/
33

Patch attached.

 Regards Kristian Klausen
