Description

This would save us lots of disk space!

At least config/binary_local-hooks/40-include_syslinux_in_ISO_filesystem depends on it though: we could ensure our custom APT repo has the correct i386 version of syslinux, but I’m not sure if it’ll be enough: the apt-get update we run after enabling i386 there might fail given no i386 indices will be available for most APT sources. Worst case, we can simply publish somewhere the i386 /usr/bin/syslinux binary we need, and download+check it without using APT.

I could find no other blocker.

… or temporarily disable all APT sources except the one for our custom APT repo, apt-get download syslinux:i386, and revert the APT sources changes.

I suspect we’ll need that disk space earlier.

  • Type of work changed from Code to Sysadmin

Actually I’ll deal with the syslinux:i386 issue simply by replacing it with the 64-bit version: see Feature #13513 for details. And then this ticket becomes purely sysadmin.

  • Target version changed from Tails_3.2 to Tails_3.3

… and thus I can only do that after we have no active branch that needs syslinux:i386, i.e. after Tails 3.2 has been released.

Deploying, running reprepro clearvanished on all repos. Then I’ll need to check what’s the deal with reprepro snapshots, likely I’ll have to delete the i386 ones manually.

Done, next reprepro updates should take the new config into account. Fingers crossed!

I’ll let our automatic GC drop them and will check after a while (once our snapshot with i386 enabled that has will expire last has expired, i.e. after Nov 24) that there’s no *_i386.deb left, nor references to i386 in the reprepro DB, nor nor anything i386 in dists/.

Seen a successful build from devel that used a Debian APT snapshot generated after deploying this change. Waiting for Bug #14735 to be fixed before I can do the same for stable. Then I’ll postpone to the release after Nov 24 (i.e. 3.4) to handle the reprepro snapshots garbage collection stuff explained above.

  • Target version changed from Tails_3.5 to Tails_3.7

Well, the APT snapshots used by our Vagrant build system (2017091504) have i386, and they will only be bumped for our next major release (early March), so I can’t complete this earlier. Until then we’ll keep some i386 binary packages. If I really need the disk space (e.g. to make progress on ARM support) I’ll speed this up.

All the pre-conditions were finally met since the 3.6 release => done!
