2012-03-19Change the /etc/mtab symlink to use an absolute pathMaxime Ripard
As systemd checks if /etc/mtab is a symlink to /proc/mount or /proc/self/mounts, we need to change it so that we can run systemd. http://cgit.freedesktop.org/systemd/tree/src/main.c#n1082 Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2012-02-01Add support for package-declared devicesMaxime Ripard
Add a way for packages to declare files they need instead of relying only on device tables, which creates files no matter if the package is indeed enabled, as we can see for busybox.

2012-01-11Rework of shutdown policy in inittabMaxime Ripard
This commit follows commit ad501b66. Start up of the busybox logging daemons were moved to an init script but the shutdown were still performed in inittab. This commit moves the shutdown policy to an rcK script that calls the stop function of all the init scripts in a reversed order.

2011-10-28/etc/profile: read in /etc/profile.d/*.sh filesThomas De Schampheleire
For custom projects, it is more maintainable to add custom profile settings in a separate file, than directly in /etc/profile.

2011-09-27fs/initramfs: refactor with fs/cpioArnout Vandecappelle (Essensium/Mind)
An initramfs is in fact the same as a cpio archive, but embedded in the kernel. So instead of duplicating the cpio infrastructure, we can simply build images/rootfs.cpio and link that into the kernel.

2011-09-27cpio: fix boot with dynamic /devArnout Vandecappelle (Essensium/Mind)
Devtmpfs doesn't get automounted by the kernel when an initramfs is used. Since cpio archives are used almost exclusively as an initramfs, the same fix should be applied to it as for the initramfs. Cfr. commit 424888e47431db738f5f9b3c6392435bfce7a842 and 10a130f91e5b947e2d2558443ff09b1686eac273.

2011-08-04initramfs/init: make sure that 0, 1, 2 fds are availableThomas Petazzoni
As the kernel doesn't automatically mount devtmpfs when an initramfs is used, commit 424888e47431db738f5f9b3c6392435bfce7a842 has introduced a small wrapper script that mounts devtmpfs before starting the real init. Unfortunately, the problem is that in this case, the init process runs without any 0, 1 and 2 file descriptors, so none of the messages/errors printed by the various initialization scripts can be seen. This is due to the fact the init process relies on 0, 1 and 2 being opened by the kernel before init is started. However, as /dev/console isn't present on the filesystem at the time the kernel tries to open the console to create the 0, 1 and 2 file descriptors, the kernel fails on this and prints the famous "Warning: unable to open an initial console". The proposed workaround is to actually open 0, 1 and 2 to /dev/console in the wrapper script, right after mounting the devtmpfs filesystem, and before starting the real init. The "Warning" from the kernel is still shown, but at least the messages from the init scripts are visible.

2011-07-25System config: split static-dev device table setting into seperate optionPeter Korsgaard
As discussed here: http://lists.busybox.net/pipermail/buildroot/2011-May/043251.html Add BR2_ROOTFS_STATIC_DEVICE_TABLE for the extra device table file(s) to create device nodes in /dev, rather than complicated logic in BR2_ROOTFS_DEVICE_TABLE, making it complicated to move between static and dynamic modes.

2011-07-20initramfs: fix boot with dynamic /devPeter Korsgaard
Devtmpfs (which is used by devtmpfs/mdev/udev options) doesn't get automounted by the kernel when an initramfs is used, causing boot failures when a dynamic /dev is used. Fix it by adding a pre-init script to mount devtmpfs before running init. Reported-by: Arnout Vandecappelle <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2011-07-18sh: Fix Buildroot sh targets to match gnuconfig targetsPhil Edworthy
sh2eb and sh2a_nofpueb gnuconfig targets are no longer supported in Buildroot. This patch replaces these Buildroot targets with sh2 and sh2a respectively, and adds sh4a targets as these are widely used. To build for devices without an fpu, the relevant toolchain flags will have to be specified.

2011-05-09Allow several device tables and split in two parts our device tableThomas Petazzoni
This allows to have a device table for all directories/files and another device table for the device files themselves. Both are needed for static /dev, but only the first one is needed when devtmpfs/mdev/udev are used. We take this opportunity to move the documentation of the device table format in a common location, package/makedevs/README.

2011-05-09Create menu entry to select device creation methodYegor Yefremov
Four methods for the creation of device files in /dev are now proposed: - static method uses device table as before - devtmpfs method enables this feature in kernel - mdev method adds mdev starting script to the file system and selects mdev itself for installation - udev method selects udev for installation All dynamic methods are based on devtmpfs, so one doesn't need to care about /dev folder.

2011-01-14fs/ext2: remove redundant BR2_TARGET_ROOTFS_EXT2_SQUASH optionPeter Korsgaard

Those folders are currently created using makedevs according to the specifications in device_table.txt.
