By default, they take the usual value of "50% of physical RAM".
As /dev/shm can be filled by anyone, and tmpfs does not trigger the OOM killer (and
can hang the machine due to a lack of RAM), I need to configure that down
in order to avoid crashes.
There is still left the /var/run/nscd tmpfs filesystem, also created with 50%
of the RAM, but at least not writeable by anyone. We could find a reasonable
low value for that, or allow configuration.

We could not start on 'filesystems', because filesystems is written as an upstart task.
Additionally, as upstart calls the postfix start/stop script and it does not act as a
daemon, we write it as a preStart/postStop job. Then we don't have monitoring or respawn,
but at least upstart does not get confused on its state.

The file contents were taken as a file path. This resulted in a system with a totally broken /etc:
lrwxrwxrwx 1 root nixbld 51 22 feb 21:45 bashrc -> /nix/store/gh71a6w50cxrl4124kxfn24yi0b7aaka-useradd
lrwxrwxrwx 1 root nixbld 44 22 feb 21:45 nix.conf -> 192.168.1.4(rw,no_root_squash,no_all_squash)
lrwxrwxrwx 1 root nixbld 58 22 feb 21:45 inputrc -> /nix/store/1czhdj7q74dc556frqrh51jyshfsxhl3-bashrc-user.sh
lrwxrwxrwx 1 root nixbld 51 22 feb 21:45 nsswitch.conf -> /nix/store/qsgsli992hd1g8245d8am9izn9xmw90x-inputrc
lrwxrwxrwx 1 root nixbld 20 22 feb 21:45 exports -> /home/sheevaplugroot
Notice that the inputrc has strange contents. In my case, that disabled me to type 's' or 'i' (at least) in any new interactive shell.
If you notice, the 'exports' symlink should point to a store file, which contents had to look like:
/home/sheevaplugroot 192.168.1.4(rw,no_root_squash,no_all_squash)
This patch achieves this later behaviour rather than the former.

problems:
- It doesn't support filenames with spaces.
- It inserts a space after the filename when tab-completing in an
"svn" command.
- Many people find it annoying that tab-completion on commands like
"tar" only matches filenames with the "right" extension.
- Lluís reported bash apparently crashing on some tab completions.
We should probably make this optional, and maybe use a subset of the
bash_completion file in the bash distribution that works.

What I want with this derivation is to allow the sheevaplug nixos to
build a tarball with all the needed files to boot. Then, this can be
unpacked into an SD card, or into a NFS/TFTP server, and then the
user can boot the system with help of the uboot console.
By now, I have only tried to build the tarball in a PC, in order
to develop the nix expressions quicker.
There is nothing written specialy for the Sheevaplug in all this,
by now.

its default behaviour is to stop the emulator (i.e. suspend the VM).
For automated tests, this is bad, because is makes the VM appear to
hang without any error message. The "werror=report" flag causes
QEMU to report the problem to the VM. As a side effect QEMU exits
very elegantly:

Using nix-push we create a channel that contains some stuff (namely

AUFS this is possible, but not on recent Linux kernels (AUFS1 over

readd r19267 (the issue should be fixed now)
Eelco Dolstra and Nicolas Pierron both kept asking me to pay attention
to the rendered manual. There is one catch: example settings such as
pkgs.kernelPackages_2_6_25 are correct however they don't render
properly. Moreover you don't want those examples to be evaluated (maybe
compiling a kernel ?) when building the manual only.
So use Strings and add a copy & paste note.
This is still a hacky. Maybe a kind of typed "verbatim" expression
should be added (?)

/nix bind mounted from a fs not rootfs.
As niksnut found, if the sources of bind mounted directories are
umounted before remounting them as "ro", a "mount -o remount,ro" on the
bind targets will not leave the filesystem properly umounted, the same
way as a "-o remount,ro" would do on a usual filesystem.
So, the trick of always remounting as 'ro' before attempting an umount seems
to fix the problem.

problem:
Nix only recognizes nixbld users which have nixbld set in extraGroups.
After installation the user was created by activate with group='nixbld'

After rebooting a conditional shell script fixed this by adding
extraGroups=["nixbld"].
This patches creates the user they way it was in the past with
group='nobody' and extraGroups=["nixbld"].
Another solution would be making nix be aware of the primary group as
well. However this would require everyone to update Nix after updating
NixOS.
