Re: [Nix-dev] Travis false-positives
Hi, Isn't travis a special case for the dynamic cache? It only runs 2 jobs at most and only when a PR comes in or a commit is done. Basically it's an extension of Hydra except that it builds PRs and doesn't save build products... Seems to me that it is fine for it to use the dynamic binary cache... Indeed. The amount of pulls from hydra.nixos.org from Travis is pretty limited, so it is ok to use for this. We just don't want a large group of people using it continuously, as the binary cache of hydra.nixos.org only generates nars on-the-fly, and it has no caching of these nars, so they put a significant load on the main Hydra machine, which is already under heavy CPU and IO pressure.

On one hand this is better than on a wiki because it stays up to date. On the other hand it's kind of weird to give other people write access to your own configurations...

Re: [Nix-dev] Limiting number of Hydra jobs
Hi Mateusz, What setting should I set so that it will only ever run specified number of total jobs? you can specify a maximum number of jobs per platform in the systemtypes table of the hydra SQL database: | # psql hydra | psql (9.2.9) | Type help for help. | | hydra=# select * from systemtypes; | system| maxconcurrent | --+--- | i686-linux | 1 | x86_64-linux |10 The default value for unspecified platforms is 2.

Re: [Nix-dev] NixOS Live CD (Graphic) Boot Failure
If only I knew what I was doing Linux Mint modprobe configs just gets a response that configs does not exist Linux Mint modprobe -c does generate a long list. The first and last entries are: alias symbol:tua9001_attach tua9001 ... ... alias symbol:zl10353_attach zl10353 If this is what is wanted, how do I send it (attachments allowed?) and if not, where should I look (or specific modprobe options and arguments)? It was also suggested that a full dmesg log would help, but that may be difficult as I am booting from the nixos live-cd. Perhaps not impossible if the output could be directed to my flash drive. I think I might be able to make text changes to the .iso (use Peazip to extract the contents and ImgBurn to regenerate the .iso), if some guidance as to what and where. I remain suspicious that this is a device identification problem (like deciding that since the drive is SATA III the controller must be as well (it's actually SATA II). Since I can look into the text portions of the .iso, where should I look? I'd like to see how it compares to the gparted live-cd .iso (it should be far less complex than the Linux Mint and certainly can run my drive).

Thanks. (I had ass-u-me-d that unstable meant bleeding-edge only.) I use UNetBootin with LinuxLive USB Creator as an alternative when I want to force a FAT32 reformat.
