@Lady It actually has a surprisingly small set of rdepends within Ubuntu. Some important packages, like Postgres, but mostly desktop software besides Postgres, Icecast, and Asterisk, and it's hard to say the latter have all too many users. There's Ruby's Nokogiri, but given the near-weekly security updates to that, I might almost prefer someone Rewrite it in Rust (or literally anything).
@aschmitz pretty sure all web browsers depend on either it directly or a fork of it (statically linked, probably, and i’m not sure how exactly the code is joined together)
if not, i’d be interested in finding out whatever they ARE using
@lanodan @Lady Kind of, yes. Though systemd and ninja only need it for building, nginx only(?) needs it for libnginx-mod-http-xslt-filter, and php uses it for php-xml. And we're both leaving out things, but I was just sort of surprised by how few things actually seem to have firm dependencies on it. On the other hand, there's enough that if it stopped working with, say, a new glibc/musl version, there would probably be a fix in short order.
