Hi, I had been working on the cruft/cruft-ng package since 2014; there where a few setbacks along the years, like mlocate -> plocate & UsrMerge transitions, but it's alive and kicking, helping to find random lost files left behind by other packages and file bugs against those from time to time to get these glitches resolved.
Recently I've been working a lot on it because I realized it would be the perfect solution to audit the disk space usage problems I'm facing at work. So I somewhat whipped up what I remembered from my own proposal https://wiki.debian.org/Cruft/purge and have now for myself a working "dh-cruft" than I can use to register dynamic files owned by some private .deb. Here "dh-cruft" is a must, I don't want to polute Debian with some random external data from downstream. This DebHelper works this way: * the "debian/cruft" list merely register the glob patterns, * and "debian/purge" list also an "rm -rf" stanza in postrm/purge. As a bonus there's now also a new "cpigs" command, working akin to "dpigs" from Debian Goodies to list the biggest volatile data producers. The plan now is to have a new option that dumps the whole matching result database as .json with individual file size for jq consumption or in my case Jupyter; this instead of implementing older requests (#291823 #487458 #527285). I know it's a very old unresolved subject that has been lurking forever here, but maybe it's the right time to look it up with a fresh view. My proposal for next steps:ยต * gather your comments here * some review of dh-cruft (I don't know Perl) * get it in the NEW queue soon * have interested packages take part; for now cruft-ng ship it's own homegrown fallback database * (later): merge dh-cruft into DebHelper when it's basically "done" * (much much later): migrate some logic from DH to dpkg itself, with a more declarative packaging style; cruft-ng is already linked with the static library libdpkg and is bound to progress at the same pace. * there is still a performance problem in cruft-ng that I wish to improve. Basic profiling can be done by setting ELAPSED=1 env var.
