I had issues building Ruby as I was using git 2.30. The error was: > file2lastrev.rb: git rev-parse failed error: could not expand > include path '~/.gitcinclude' The default system git config includes paths making use of `$HOME`, but that env variable gets removed when building:7070b1b196/tool/lib/vcs.rb (L546-L547)
It works with git `>= 2.32` thanks to the `GIT_CONFIG_SYSTEM` feature which gets set to a Null IO in order to override the system gitconfig.7070b1b196/tool/lib/vcs.rb (L549)
