<mark_weaver>you could find out by entering the store monad REPL (see section 4.5 of the manual) and running 'package->derivation' on various packages in (gnu packages bootstrap) and (gnu packages commencement)
<mark_weaver>and btw, notably: the sha256sum is verified after it is downloaded, but if the file is already there in your source directory, it is *not* checked.
<rekado>trying to build R again, now that the bootstrap tarball's permissions have been reset.
<mark_weaver>so, for example, if at some point in the future we update the bootstrap guile, you'll need to explicitly remove the file from your source directory in order to have 'make' get the new one.
<rekado>pcap-linux is not built at all. Only netfilter-linux exists. Since iptables also doesn't work for me out of the box, I think I need to load some kernel modules to make netfilter and thus tcpdump work.
<civodul>and "pcap-linux" is another backend that does not rely on netfilter?
<alezost>oh! "nonsensical" didn't come to my mind :-)
<mark_weaver>civodul: fyi, rekado experienced a surprising issue that took a while to debug. Apparently one of his coworkers had added the execute bit to gnu/packages/bootstrap/x86_64-linux/guile-2.0.9.tar.xz, and this had the effect of changing the hashes on all his builds.
<mark_weaver>I see a test failure in python-3: ERROR: test_write_filtered_python_package (test.test_zipfile.PyZipFileTests)
<mark_weaver>ValueError: ZIP does not support timestamps before 1980
<mark_weaver>I guess that's related to zeroing the timestamps in the source tarball
<mark_weaver>civodul: it occurs to me that if we fixed hydra's handling of -C in the presence of deduplication, then we could get a much faster removal of .links/* almost for free
<mark_weaver>the idea would be to check the number of hard links on each file as it's removed from the store.
<mark_weaver>and only when the link count goes to 2 is the file really going to be deleted. only then should its size be included in the accounting of how much has been freed, and in that case the .links/* file can be removed immediately.
<mark_weaver>however, it's probably not entirely airtight, so it would be good to have an option to run a full pass over .links/* looking for links to remove.
<tyrion-mx>mark_weaver, hey :) I had the exact same error after reinstalling anyway ..
<mark_weaver>tyrion-mx: can you email email@example.com with the details?
<tyrion-mx>the only strange thing that happened is that I forgot to use sudo on the guix system init command, so it failed at the end, but then running it again with sudo failed with the same grub error
