55 hours, but:
Mar 10 08:30:24 buildd-uploader[15179]: 1 jobs to upload in upload: linux_4.4.4-1_m68k.changes
Mar 10 08:33:45 buildd-uploader[15179]: linux: not taken by you, but by buildd_m68k-vs93. Skipping.
Mar 10 08:33:45 buildd-uploader[15179]: dupload successful.
So one qemu is as fast as eight CT60, which should be still a bit fast than
an 060 Amiga. Hmm.

I use LVM, I don't trust btrfs yet and I don't want to ruin my partitions
again. Setting up the chroot is pretty fast. Updating the chroot (from
sbuild) takes an hour, even though it is disabled in the global and local
config (do I need to disable APT_UPDATE_ARCHIVE_ONLY as well?). Outside the
chroot with apt-get update, and a manual update with schroot takes 15-20
minutes, not 60. Whats so special about doing this with sbuild?
Anyway, I have installed eatmydata again, did not seem to help yet. Maybe
with the next package.
