Hi, cat staff and useless humies! I've done some data mining on bug reports that include a "System Information" section that reportbug adds.
This information is notoriously corrupted and/or includes write-in stuff. I tried to do my best to recover data when it could be done unambigously; many corruptions are obvious (like "=" -> up to "=3D3D3D"), others are mangled beyond recognition. All the percentages below thus use non-null non-"unable to determine"/etc count as 100%. The data is up to bug #850909 filed 2017-01-11 05:39:02 (took me a while to write this, sorry). Graphs below might be unreadable if your mail client's chosen font lacks the U+2800..U+28FF range, and fallback font is pre-stretch FreeFont Mono; this is the case for libvt terminals on the default install. The prose should be enough, I hope. +=========+ | ᴄʜᴀʀᴍᴀᴘ | +=========+ The main thing I was looking for is the use ratio of ancient locales. Here's the graph of "charmap" field other than UTF-8, excluding unconfigured (aka C) (mojibake->mojibake is no regression). As reportbug started including charmap information late, a good part of the transition is lost -- Oct 2004 already has 43% UTF-8. max=51%; X scale: month ⠀⠀⢠⠀⠀⠀⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⣄⣾⠀⠀⣦⣿⣿⡄⠀⡆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⢠⣿⣿⣄⡇⣿⣿⣿⡇⠀⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣷⣿⣿⣿⣇⡄⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⡇⡀⢀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⢸⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣸⣿⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣶⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣧⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣾⣧⣤⣶⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⡀⠀⠀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣤⣾⣇⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣧⣿⣦⣠⣷⣄⣰⣠⡀⢀⠀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣾⣷⣷⣠⡀⠀⠀⡀⢸⣿⡄⠀⠀⠀⠀⠀⡄⣠⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣾⣿⣾⣿⣿⣶⣴⣤⣠⣷⣷⣿⣧⣰⣴⡄⣤⣀⣀⣀⣀⣠⣄⣀⣄⢀⢰⡀⣀⣀⣀⢀ Oct 2004 Jan 2017 Enlarged: max=7%; X scale: month ⠀⡄⡆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⣿⡇⠀⠀⠀⠀⠀⠀⠀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⣿⣧⠀⠀⠀⠀⠀⢰⢀⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⡀⣿⣿⡄⠀⠀⠀⢰⢸⢸⣿⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣷⣿⣿⣷⡆⡄⠀⢸⣸⣸⣿⠀⡀⡄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⡄⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣷⣿⡆⣿⣿⣿⣿⡄⣿⣷⢠⡄⢠⠀⡀⡀⣦⠀⢰⠀⠀⡇⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣼⣷⣿⣿⣿⣿⣿⣿⣾⣦⣧⣿⣼⣶⣶⣆⡆ Jan 2012 Jan 2017 Avg for 2016+: 0.8%. +======+ | ɪɴɪᴛ | +======+ While, as expected, releases that defaulted to sysvinit get gradually replaced, resulting in a downwards trend, things look differently if we look at unstable only: after a forced transition (much of which is again lost because of system information added late), somewhere around the start of 2016 it plateaued and didn't move except for noise since. 17 reports with upstart and 4 with runit are a rounding error. max=44%; X scale: week ⠀⣇⠀⢰⠀⡆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⣿⠀⢸⢸⡇⠀⠀⠀⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⣿⢰⣾⣸⣷⠀⠀⠀⡇⠀⡆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⣿⢸⣿⣿⣿⠀⡆⠀⡇⠀⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⢠⣿⣿⣿⣿⣿⠀⡇⢀⡇⡀⡇⠀⠀⠀⠀⠀⠀⡄⠀⡇⠀⠀⢠⠀⠀⠀⠀⠀⠀⠀⡇⢸⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣼⣿⣿⣿⣿⣿⠀⣿⣼⡇⣧⣧⡀⡀⠀⠀⡀⠀⡇⡆⣧⠀⡄⢸⠀⢸⠀⠀⢀⠀⠀⡇⢸⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⡆⠀⠀⡀⠀⠀⠀⢀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣦⣿⣿⣿⣿⣿⣇⡇⡇⡄⣿⠀⣧⡇⣿⡇⡇⢸⡇⢸⡀⠀⣾⡆⠀⡇⢸⣠⢸⠀⠀⣤⠀⠀⠀⡀⠀⠀⡇⠀⠀⡇⠀⠀⡄⣾⡀⡄⠀⡆ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⣿⣷⣿⣤⣿⣧⣿⣷⡇⢸⣿⣼⡇⡀⣿⣿⣤⣷⣾⣿⢸⡇⡆⣿⣠⡇⡄⣿⡄⢠⡇⡆⠀⣧⣠⠀⡇⣿⡇⡇⣤⡇ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣿⣿⣿⣿⣿⣿⣿⣿⡇⣿⣿⣿⣧⣷⣿⣿⣿⣿⣿⣿⣼⡇⣷⣿⣿⣿⣷⣿⣧⣼⣇⣧⡆⣿⣿⣴⡇⣿⡇⡇⣿⡇ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣇⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣇⣿⣿⣿⣧⣿⣇⣷⣿⡇ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇ Dec 2014 ↑ Jan 2017 Avg for 2016+: 14%. +=======+ | ꜱʜᴇʟʟ | +=======+ It's /bin/sh not the interactive shell -- that's what reportbug says. 2014 2015 2016+ -----+-------+-------+-------+ dash 15316 12509 12296 bash 1505 823 705 lksh 83 75 80 mksh 21 13 zsh 1 +==========+ | ʟᴀɴɢᴜᴀɢᴇ | +==========+ 2016+: en | 7307 de | 1753 fr | 1316 C | 1028 es | 275 it | 229 ru | 212 POSIX | 170 ja | 151 pt | 107 pl | 99 zh | 80 fi | 51 nl | 50 cs | 41 el | 24 bg | 21 hu | 21 ca | 17 da | 17 sv | 17 nb | 13 he | 12 sl | 9 gl | 8 ro | 8 is | 6 sk | 6 eu | 5 be | 4 lt | 4 ml | 4 ar | 3 th | 3 uk | 3 fo | 2 ia | 2 id | 2 mn | 2 nn | 2 tr | 2 eo | 1 et | 1 ko | 1 nds | 1 zen | 1 +======+ | ᴀʀᴄʜ | +======+ Reportbug reports architecture as "arch (uname -m)" (no parentheses if both are the same); there's a bunch of reports with "uname -m" -- I guess some derivative produces them this way. 2016+: amd64 11558 i386 1124 (i686 881, x86_64 229, i586 14) armhf 110 (armv7l 106, armv6l 1, aarch64 1, qemu 2) x32 58 kfreebsd-amd64 52 powerpc 42 (ppc 33, ppc64 9) hppa 34 armel 26 (armv5tel 25, armv6l 1) arm64 19 (aarch64 18, qemu 1) hurd-i386 16 ppc64el 15 mips64el 6 sparc64 6 mipsel 5 (mips64 4, mips 1) kfreebsd-i386 4 mips 4 (mips64 2, qemu 2) s390x 2 ppc64 1 ia64 1 Mangled/derivative: x86_64 48 armv7l 27 armv6l 9 i686 9 +===============+ | ꜰᴏʀᴇɪɢɴ ᴀʀᴄʜꜱ | +===============+ Lots of noise, thus only tidbits. 2016+: 57% of amd64 have i386.

Core counts for >1? UTC hours or days of week when bugs are filed? Kernels that've been in the archive vs those that haven't?
