Usually, these tools run on x86, which creates a problem for packages. I would like to install packages onto the image as it's built. So I've been experimenting with variations of pkg -c DESTDIR add package files I'm running into a few problems but I think they can all be solved. Only the first is critical; the rest are relatively minor annoyances. 1) Pre-install/post-install scripts. These obviously don't work since the DESTDIR is for a different architecture. At least for post-install, it should be possible to record which packages still need their post-install scripts run and arrange to run them after first boot. I'm picturing an rc.d script that invokes pkg with appropriate options to find all packages that still need their post-install run and runs them. This won't work for pre-install, but those are rarer and we can hopefully work around them on a case-by-case basis. 2) The chroot happens before opening the package files. It's possible to work around this by copying all of the package files into DESTDIR first, but that's both time-consuming and rather awkward. (And quite tricky if you're installing directly onto a mounted image that has very little free space.) It should be feasible to open the package files first and then chroot. Then the actual installation still happens entirely inside DESTDIR. If you have a directory full of the package files, you can nullfs-mount it within the chroot rather than copying its contents in. Nullfs mounts are great for crossing chroot barriers in such situations. Using them does make your scripts more complex, because you need abort and exit handling in the scripts to undo the mounts no matter what kind of exit the script encounters. If you don't, you end up leaving nullfs mounts that make later things fail (such as running the script again, or trying to clean/remove a chroot tree). I'd rather avoid nullfs since it requires root or at least enabling user mounts. If one wanted to avoid opening all packages to start off, just opening the package directory and using dirfd() and openat() to do opens later could also work. Without looking at the pkg code it might require fewer changes to the existing code flow. -- Brooks pgpDOAFZTRUbP.pgp Description: PGP signature

The new installation on FreeBSD.org, of course, would test FreeBSD-10 under (heavy) server load. Just one word from an ordinary user - this is perfect idea to test things in the real world scenario in a dedicated environment because this will show problems and force solutions very quickly. Some more serious tasks may be also a good playground to test stability of the stable branch and make sure they will not propagate issues to the production stable platforms around the world. I really love FreeBSD for the clean, simple and elegant yet still very powerful solutions. Some features are still behind, some features are pioneer, still smart and experienced personnel decisions behind the scenes produces impressive results. I am sure this is also a good decision.

Based on my brief experiments yesterday, 6.X is the last release where accessing floppy disks carry less than a 10% risk of a panic. Unless somebody fixes the fdc driver to work in -current, I intend to dust of my axe and cut it from the tree later this spring. Yes, I did try at the time 9 was current (to make fancy DOS floppies for BIOS for the old machine). I remember I only had an issue with PCMCIA-attached floppy drive (that uses fdc(4) afair), which didn't work then (but I am user I used those long time ago). Maybe the issue you are seeing is similar to my PCMCIA-based floppy problem - I'd be happy to have it fixed for recovery of old boxes.

It's (amongst other things) ISA-DMA being børken (try something different that /dev null btw :-) and bounce buffers for same panicking the system.

And as long as there is no automatic can taster doing quality assurance of the produced cans, then foul cans will go unnoticed until a dog pukes all over the carpet :-) Isn't this the idea of HEAD? For this to change, we really need to catch up on years of neglect in e.g. src/tools/regression/. I really applaud the people doing the thankless job of changing this.

Re: 7+ days of dogfood
I've ran 8-CURRENT amd64 desktop which evolved to 8-STABLE and 9-STABLE now, without real deal breakers. All rougher edges I reckon from -CURRENT days gradually went away, but system was very usable then too. -- View this message in context: http://freebsd.1045724.n5.nabble.com/7-days-of-dogfood-tp5785452p5785794.html Sent from the freebsd-current mailing list archive at Nabble.com. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Second, I wrote src/tools/tools/sysbuild to specifically address the issue of being able to work, while running -current. sysbuild allows you to build your system into an empty partition while you're working (= good test of scheduler btw), then test boot the new system, and fall back to the old if it caused too much trouble. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
