There is a new pull request by olafmersmann against master on the void-packages repository

https://github.com/olafmersmann/void-packages master
https://github.com/void-linux/void-packages/pull/27779

shutils/chroot.sh: move homedir to /tmp/fake-home.
starship tests fail if /tmp is $HOME because they create files inside
/tmp and compare the shortend path to an expected path. If /tmp is
$HOME, starship contracts it to ~ which does not match the expected
value.

A patch file from https://github.com/void-linux/void-packages/pull/27779.patch is attached
