…nt drive than TEMP When running flux bootstrap from a drive (e.g. D:\) different from where %TEMP% lives (typically C:\), filepath.Rel fails because Go can't compute relative paths across different drive letters. The original code converted absolute paths to relative as a workaround for a kustomize bug (kubernetes-sigs/kustomize#2789) that was caused by go-getter. Since kustomize dropped go-getter in 2021, absolute paths work fine now. Instead of hard-failing when filepath.Rel errors, keep the absolute path as a fallback.

Fixes #1153
When running
flux bootstrap(orflux install) from a drive different than where%TEMP%lives (e.g. working dir onD:\, temp onC:\), Go'sfilepath.Relreturns an error because it can't compute a relative path across Windows drive letters. The CLI just propagated that error and died.The relative path conversion was originally added as a workaround for kubernetes-sigs/kustomize#2789, which was caused by kustomize's old
go-getterdependency. Kustomize droppedgo-getterback in 2021 (kubernetes-sigs/kustomize#3586), so absolute paths work fine now.The fix: when
filepath.Relfails, keep the absolute path instead of returning an error. The relative conversion still happens when possible (same drive), so behavior on Linux/macOS is unchanged.I don't have a Windows box to test on directly, but the code path is straightforward — the change is from
if err != nil { return nil, err }to just skipping the relative conversion on error. @kitforbes or @domoran mentioned being able to test on Windows if someone provides the fix.Signed-off-by: Varun Chawla varun_6april@hotmail.com
