| minute | bluerise: oh neat | 00:39 |
| digitalrayne | nice! i was looking at the firefly itx, hope to replace my desktop with one of these | 00:42 |
| digitalrayne | i think an itx carrier board for reform would be pretty cool | 00:42 |
| digitalrayne | i've got a 50% complete schematic around here somewhere | 00:43 |
| bluerise | one of the reasons I got the ITX version, because I have a nice case (Dan Cases A4) | 00:44 |
| bluerise | It boots android... | 00:44 |
| bluerise | wonder if I can port regular U-Boot instead of this ... thing | 00:45 |

| josch | well, it's not like i ever was a fan of ext2 :D I'm not attached to it | 06:58 |
| josch | the reason i was initially implementing everything using genext2fs was to support bit-by-bit reproducible images | 06:58 |
| josch | ah vagrantc joined just at the right time :D | 06:58 |
| josch | and bit-by-bit reproducible ext4 images are just not possible right now because of subtly different timestamps in the filesystem that the image gets generated from | 06:59 |
| josch | this is solved by using tarballs as the carrier of the information | 06:59 |
| josch | using genext2fs would've allowed me to upgrade to mkfs.ext4 (once it supports tarballs) nearly as a drop-in-replacement | 07:00 |
| josch | but 2 years ago, when i filed https://github.com/tytso/e2fsprogs/pull/118 I just didn't expect this feature not getting merged for that long | 07:01 |
| josch | especially because Ted did talk favourably about it to me privately as well as on public lists | 07:01 |
| josch | like for example at the bottom of this mail: https://lists.debian.org/20231112052724.GC39417@mit.edu | 07:02 |
| josch | wording like "will shortly integrate" always made me hopefull that we soon can get rid of ext2 | 07:03 |
| josch | while at the same time being able to produce bit-by-bit reproducible images | 07:03 |
| josch | ext2 as it is generated from genext2fs just has too many practical issues like the fixed 128 byte inode size | 07:08 |
| + chomwitt (~chomwitt@2a02:587:7a17:f700:1ac0:4dff:fedb:a3f1) | 07:08 | |
| josch | which does not allow for subsecond timestamp precision or timestamps beyond 2038 | 07:08 |
| josch | so when minute talked about these fsck problems it was just the last straw for me | 07:09 |
| josch | the problems with ext2 (as generated by genext2fs) just far outweigh its benefits and there is no solution to https://github.com/tytso/e2fsprogs/pull/118 in sight | 07:09 |
| vagrantc | reproducible filesystems are hard. | 07:20 |
| josch | true, but there is code that makes it possible even with ext4 | 07:21 |
| josch | so it saddens me that it gets neglected that much by e2fsprog maintainers :( | 07:21 |
| vagrantc | :/ | 07:24 |
| josch | vagrantc: with the changes from this pull request you can produce bit-by-bit reproducible ext4 images by setting the environment variable E2FSPROGS_FAKE_TIME to a reproducible epoch (or just SOURCE_DATE_EPOCH), give a reproducible UUID with -U and a reproducible htree seed with -E hash_seed | 07:25 |
| vagrantc | josch: must merge! :) | 07:26 |
| vagrantc | hrm. | 07:26 |

| digitalrayne | ok i think all the kinks are worked out, and apm & sysctl can report battery charge, current, voltage, AC and charge state for reform on OpenBSD now with the driver i wrote, will try to clean it up and get it committed, wish me luck | 08:20 |
| digitalrayne | also poweroff works on halt -p with this driver | 08:20 |
| digitalrayne | i think the only major thing now is supporting the onboard sound, still no video accel or anything but using the uboot framebuffer is perfectly ok for most stuff tbh | 08:21 |
| digitalrayne | i'm hoping this will also work for the pocket lpc but shouldn't be a big deal to address if it doesn't | 08:22 |
