MORIN Date: Sat, 27 Feb 2016 22:03:15 +0000 (+0100) Subject: support/download: really, really make git archives reproducible X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=87731820926cd6f51879d7b89687bfec2e615b3d;p=buildroot.git support/download: really, really make git archives reproducible The way we use it, gzip will store the current time in the header, which leads to unreproducible archives. Fix that by telling gzip to not store the name and date of the file it compresses, with the -n option. Since it compresses its stdin, there was already no filename stored; now there's even no date stored. Note: gzip has had -n since at least 1.2.4, released in 1993, so virtually every gzip out there nowadays has it. Signed-off-by: "Yann E.
