chezmoi on Android can't connect to Internet/DNS about chezmoi HOT 4 OPEN

After switching to Termux's chezmoi I found out that after diffing with Termux build (and when all externals are downloaded), then diffing with official build works again (using cached externals).
So turns out that android build without some Termux patches works only partially

$ /data/data/com.termux/files/home/.local/bin/chezmoi diff
chezmoi: Get "https://github.com/macvk/dnsleaktest/raw/HEAD/dnsleaktest.py": dial tcp: lookup github.com on [::1]:53: read udp [::1]:48172->[::1]:53: read: connection refused

$ /data/data/com.termux/files/usr/bin/chezmoi diff
*diff here*

$ /data/data/com.termux/files/home/.local/bin/chezmoi diff
*diff here*

UPD: I did some research and Termux actually has a patch for golang: termux/termux-packages/packages/golang/fix-hardcoded-etc-resolv-conf.sh which fixes DNS resolving on Android

UPD2: This is actually a bug of golang on Android: golang/go#8877

This is something to do with your system. This is not a bug in chezmoi.

Thanks for the further investigation and apologies for the too-hasty fix.

If I understand correctly, there are two ways for chezmoi to work around this bug in Go:

1. Build the Android binaries with cgo. This will require the Android SDK.
2. Add a user-configurable DNS server in chezmoi's config and use that on Android.
3. Use https://github.com/mtibben/androiddnsfix.

Of these, (1) is the cleanest but might not be supported by goreleaser (the tool chezmoi uses to build its release binaries), (2) has poor user experience, and (3) strikes me as too much of a hack.

Does the Termux-built chezmoi binary have this same problem?

Patch in Termux is for golang itself. So any binaries built in Termux are patched:
