* Warn the user about the usage of output/target as the root filesystemThomas Petazzoni2012-11-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 ext2Arnout Vandecappelle2012-11-142-7/+6
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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.

* New top-level directory: systemThomas Petazzoni2012-11-0455-755/+0
| | | | | | | | | | | | | | | | | | | | | | 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.

* Remove unused .fakeroot.* mechanismThomas Petazzoni2012-04-192-4/+0
| | | | | | | | | | | | | | | | | | | There used to be a mechanism using which packages could leave a .fakeroot.<something> file which could contain commands to be executed within the fakeroot environment. Since this mechanism is no longer used by any package, remove it from the common infrastructure. The latest user was nfs-utils, which used this mechanism to do the "make install" as root, since doing otherwise was not supported. But since 16e7b8255c82815126a2c502c3787d442d254a86, nfs-utils has been upgraded and converted to the package infrastructure, and this hack is no longer necessary. Another past user was the ltp-testsuite package, for the same reason, and since a72a670489547a3ca645ff7c3a0d9c3fb66eab51, the fakeroot hack is no longer needed.

| | | | | | | | | | An initramfs is in fact the same as a cpio archive, but embedded in the kernel.

* cpio: fix boot with dynamic /devArnout Vandecappelle (Essensium/Mind)2011-09-272-5/+26
| | | | | | | | | | | | 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.

* initramfs/init: make sure that 0, 1, 2 fds are availableThomas Petazzoni2011-08-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
