FWIW they fixed the DNS over TCP issue. [1] The only DNS issue I've run into is a lack of IPv4/IPv6 DNS lookup ordering preference like glibc's /etc/gai.conf. Useful in data-centers where 100% of lookups on specific nodes/roles are and always will be IPv4

I too use Alpine on just about everything. I'm happy with it. I do wish it would keep one old kernel around after upgrades but I worked around that.
