* linux: Do not force GZIP initramfs compressionValentine Barshak2013-07-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initramfs compression does not make much sense for the architectures that support compressed kernel images because in this case the data would be compressed twice. This will eventually result in a bigger kernel image and time overhead when uncompressing it. The only reason to use compressed initramfs is to reduce memory usage when the kernel prepares rootfs, and both the unpacked filesystem and initramfs.cpio are present in the memory. Buildroot attempts to force GZIP compression for initramfs, however it doesn't always work because initramfs compression mode depends on RAM disk compression supported by the kernel. Thus, CONFIG_INITRAMFS_COMPRESSION_GZIP depends on CONFIG_RD_GZIP. If CONFIG_RD_GZIP is not set, setting GZIP initramfs compression will have no effect. Besides, the kernel also supports other compression methods, like BZIP2, LZMA, XZ and LZO. Forcing the good old GZIP does not really make much sense any more. This removes initramfs compression settings from Buildroot, so that the default value preset in the kernel config is used, which is CONFIG_INITRAMFS_COMPRESSION_NONE. If initramfs compression is still needed, it can be set in the kernel config (using make linux-menuconfig) Signed-off-by: Valentine Barshak <gvaxon@gmail.com> Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* package/genext2fs: add host variantYann E. MORIN2013-06-031-0/+1
| | | | | | | | | | | | | | | | | | | | | genext2fs is built only if the user selected an ext2 root filesystem. However, some use-cases can't live with the full target/ dir on the root filesystem, and requires separate partitions (eg. for /usr). In this case, the user would not select an ext2 root fs in the Buildrooot menu, and would only generate a tarball of the rootfs. This tarball would then be used from a post-image script to build the actual required FSes. But then, genext2fs is not built, since the ext2 root FS was not selected. As for the other filesystem generators, provide a host variant of genext2fs (genext2fs is already host-package aware, so only needs adding a Kconfig entry). Signed-off-by: "Yann E.

* fs/ext2: further fix to the UUIDYann E. MORIN2013-05-291-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turned out that setting a nil-UUID is no better than clearing it. What currently happens is as follows: - first, genext2fs does not generate a UUID - then we tune2fs to upgrade the filesystem - then we run fsck, which generates a random UUID - then we re-run tune2fs to set a nil-UUID So, on the target, if the file system is improperly unmounted (eg. with a power failure), on next boot, fsck may be run, and a new random UUID will be generated. *However*, fsck improperly updates the filesystem when it adds the UUID, and there are a few group descriptor checksum errors. Those errors will go undetected until the next fsck, which will then block for user input (bad on embedded systems, bad). Fix that by systematically generating a random UUID _before_ we call to fsck. A random UUID is not so bad, after all, since there are already so many sources of unpredictability in the filesystem: files date and ordering, files content (date, paths...) which renders a fixed UUID unneeded. And it is still possible to set the UUID in a post-image script if needed, anyway. Signed-off-by: "Yann E.

* fs/ext2: add ability to build ext3/4 tooYann E. MORIN2013-04-123-10/+105
| | | | | | | | | | | | | | | | | | | | | | Use the host-e2fsprogs to tune2fs the generated rootfs.ext2 image, and upgrade it to either one of ext2, ext3 or ext4. Since calling tune2fs may require running e2fsck (tune2fs will warn to do so when certain FS options are changed), we systematically call e2fsck. This makes the code path simpler, and as a side-effect checks that genext2fs did not generate garbage. In turn, e2fsck will unconditionally add a UUID to the filesystem, which is bad for reproducibility, so we call tune2fs again to remove the UUID. This does not require checking the filesystem. To ensure compatibility of Buildroot's .config, leave ext2 as the default. Boards' .config can override this at will. Signed-off-by: "Yann E.

* fs/common.mk: delay evaluation of variablesArnout Vandecappelle (Essensium/Mind)2013-01-2011-37/+37
| | | | | | | | | | | | | | | | | | | | | This makes things easier to understand and more consistent with the pkg-infra. For example, it removes the need for '$$@' in the CMD variables of fs/*/*.mk. It also makes it possible to update the variables later, e.g. in the package override file. It also makes sure that the date will be recorded correctly in Yann E. Morin's patch that logs the MESSAGE macros to a file. The fs/*/*.mk must be updated as well because the '$@' shouldn't be quoted anymore in the CMD variables or the hooks. The $(eval ...) for the dependencies is redundant, because the $(ROOTFS_TARGET) variable is already eval'd. Note that it is only redundant if the evaluation of the uses of the variable is also delayed.

* 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.

* 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.

* System config: split static-dev device table setting into seperate optionPeter Korsgaard2011-07-251-1/+2
| | | | | | | | | | | | | 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.
