Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Find the system's MD5 binary. Different binaries calculate MD5 checksums on different systems. Try a couple known programs and only calculate and verify the checksum if they exist. This should silence warnings on eg OpenBSD.
