Subject: Re: tor web-browser doesn't work on musl
Hi, Rich. Did you receive my other email that was sent to both mailing
lists (Tor and Musl)?
In it I listed a few possibilities and 1 of them was to
statically-link the binaries to musl.
Between other possibilities I included having separate binaries for
glibc and musl, but you show that's a bad idea.
Could you comment on the other email too, letting the Tor developers
also aware of this and showing that the best outcome would be
static-link to musl?
I wonder if there would be any difficulty for them to do so... Or
rather no difficulty, but lack of desire for change. I hope they're
flexible.
