fs/common: Create initial console device

2012-11-21T10:31:33+00:00

A /dev/console node must be present in rootfs when the Linux kernel boots otherwise the kernel will print the following warning: "Warning: unable to open an initial console" This is because when we use an initramfs the /dev directory is not populated at this point. This can cause problems when a program (e.g ldso with early debugging enabled) opens a standard file descriptor for read/write before these descriptors are actually created by the init process later on.

Warn the user about the usage of output/target as the root filesystem

2012-11-17T16:12:49+00:00

A very common mistake done by our users is that they use output/target/ directory as their root filesystem. Even though this is loudly documented in our Buildroot manual, people don't read documentation, so it is not sufficient. This patch adds a text file named output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why output/target isn't appropriate to use as the root filesystem. The process is: * At the beginning of the build, right after the skeleton has been copied, support/misc/target-dir-warning.txt is copied to output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM * In the filesystem images creation code, this file is removed before launching fakeroot, and restored right after that, so that this file is not present in the generated root filesystem images. Note that the file has not been added to the default skeleton for two reasons: * It would have annoying to have in our source tree a file named in capital letters inside system/skeleton/ * The proposed way works even if the user uses a custom skeleton.

iso9660 fs: use cpio initrd instead of ext2

2012-11-14T21:53:25+00:00

The ext2 initrd is pretty broken, because it requires an additional root=/dev/ram0 command line parameter, and a /init to mount devtmps that isn't there in out ext2 rootfs. So just use a cpio instead. Note that there is no check if the kernel supports initramfs or the selected compression method. Also removed a bit of dead code in iso9660.mk.

cpio/initramfs: clarify their use in the help text

2012-11-07T10:48:13+00:00

Recent mails on the list show that it is not very clear how to create an initial RAM fs with buildroot. So make this more explicit in the cpio and initramfs help texts. Hopefully this will reduce the /init debugging we have to do. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Peter Korsgaard

New top-level directory: system

2012-11-04T11:51:08+00:00

This directory groups the following elements: * the default root filesystem skeleton * the default device tables * the Config.in options for system configuration (UART port for getty, system hostname, etc.) * the make rules to apply the system configuration options Even though the skeleton and device tables could have lived in fs/, it would have been strange to have the UART, system hostname and other related options into fs/. A new system/ directory makes more sense. As a consequence, this patch also removes target/Makefile.in, which has become useless in the process.

fs/skeleton: remove /etc/TZ

2012-10-24T07:16:50+00:00

Defaulting to UTC (which is what uClibc will default to when /etc/TZ is missing) seems more sensible than US Mountain Time Zone in the default rootfs skeleton. Signed-off-by: Peter Korsgaard

use portable printf instead of echo -e, needed for MacOS X buildhost

2012-10-06T11:05:26+00:00

echo -e is not a portable way to do this, better use printf. Works with MacOS X. Signed-off-by: Waldemar Brodkorb Acked-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Peter Korsgaard
