Description

This is with initramfs-tools 0.127. I guess our patches didn’t make it into Debian yet, so I’ll check and build+upload a new custom package with our patches applied.

You may also need a more recent cpio. We are using a patched version Debian.

With cpio 2.11+dfsg-6 and initramfs-tools 0.127.0tails2 (that has your patch for Debian bug 845034 applied) the initrd is not reproducible. Running diffoscope on two of these initrds says:

--- new-iso/live/initrd.img
+++ old-iso/live/initrd.img
│┄ No file format specific differences found inside, yet data differs (ASCII cpio archive (SVR4 with no CRC))

Actually it builds reproducibly once the files metadata in the SquashFS does.
