GMP GCC C++ Hurd cross-build failure on core-updates
You could try seeing what they're doing here to cross-build https://github.com/flavioc/cross-hurd It worked last time I ran it (which was admittedly a while ago)
Re: Status of hibernation (suspend to disk) in Guix
> 2. Does hibernation work in case of a swap-file inside a root-partition inside a luks-encrypted device? Just posting to confirm that this does work (with BTRFS as well; single drive only, not RAID).

I think that's a great idea; I'm not sure if you've noticed, but mcron is now doing that for the job it runs, so it'd be consistent if Shepherd also did that. -- Thanks, Maxim

I went through the installation without any problems. And I tested the installation of 'guix-binary-1.4.0rc2.armhf-linux.tar.xz' on top of a very bare-bone embedded OS, which went mostly fine apart from gotchas that are attributed to that strange busybox environment (I needed guix pack to help bootstrap the needed dependencies), and some changes to the install script to accommodate that use case (see #60068). It seem to run fine there. Thanks for the RCs! -- Thanks, Maxim

shepherd: prefix output with service names?
Hi Guix, here is some output from “guix system reconfigure”: --8<---cut here---start->8--- … activating system...

If it has, it prints a warning (but it continues). For instance: ``` $ dd if=/dev/zero of=swap bs=512 count=1 seek=1000 1+0 records in 1+0 records out 512 bytes copied, 0.000234313 s, 2.2 MB/s $ mkswap swap mkswap: swap contains holes or other unsupported extents. This swap file can be rejected by kernel on swap activation! Use --verbose for more details. Setting up swapspace version 1, size = 496 KiB (507904 bytes) no label, UUID=3c5920cb-04ee-4713-8008-c2c1bebc2f6f ``` [1]: https://github.com/util-linux/util-linux/blob/master/disk-utils/mkswap.c Since it's unlikely that the file will change its block arrangement on disk, and enlarging it requires another invocation of `mkswap`, it's probably enough to tell the user to check for such warnings on `mkswap` invocation (in section "(guix)Keyboard Layout, Networking, and Partitioning"), and then instructing them to use `filefrag` in "(guix)Swap Space" should be ok. I can work on an additional patch for that, but I can't ensure that it'll be ready before 1.4.0 (I'm not in the dev team, so I don't know what the planning for the release is ).
