commit ae714772c38410a0169f2c76a14a64a62c0daff0 parent fd5d1dab4f4aed84b6cfacc3a2ee845f7bb9a91b Author: Axel Gembe <derago@gmail.com> Date: Sun, 23 Jun 2019 02:40:29 +0200 AppImage: Make build reproducible We build our own mksquashfs from squashfskit which supports generating reproducible squashfs images. We use a small wrapper script to remove the -mkfs-fixed-time which appimagekit passes but squashfskits mksquashfs does not support. ----- taken from Electron-Cash/Electron-Cash@dd1f106f4f500fbf993094cf73da89a5745a0e2c see AppImage/AppImageKit#929 Diffstat:
