* fs/cpio: don't extend packages' permissions tableGravatar Yann E. MORIN2018-03-311-2/+4
| | | | | | | | | | | | | | | | | | | | | | | Currently, when we build a cpio filesystem without static devices, we shoehorn the /dev/console node as if it were specified by a package. This means that this device is added for all filesystems as well, not just the cpio. But if we disable cpio, that device is not created for other filesystems. This is not very clean, and may break expectations. Instead, use an explicit mknod as part of the _CMD, as we know it's going to run under fakeroot. This is still visible to all filesystems built after cpio, and not to those built before it, though. [Peter: ensure /dev exists, simplify comment] Signed-off-by: "Yann E.

* fs/cpio/init: preserve argumentsGravatar Gaël PORTAY2018-02-261-1/+1
| | | | | | | | | | | Use "$@" instead of $* to preserve arguments containing spaces. The shell expands "$@" as "$1" "$2" "$3"... while it expands $@ as $1 $2 $3. With the second form, we loses spaces in positional parameters.

* fs: make it behave a bit more like the package infraGravatar Yann E. MORIN2018-01-031-1/+1
| | | | | | | | | | | | | | Currently, to register a filesystem, one has to call: $(eval $(call ROOTFS_TARGET,blabla)) This is very unlike the package infrastructure, where the name of the package is automatically guessed by the infra. It turns out that we can now do that for the filesystem infra too. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
* fs/cpio: use a post-gen hook rather than a post-target ruleGravatar Yann E. MORIN2017-11-301-5/+6
| | | | | | | | | | | | | | | | | We already have a mechanism for running stuff after the filesystem is generated, and that's called post-gen hooks. Use those hooks. Note: for cpio (and unlike ext2 previously), the dependency chain was correct, in that the post-target rule correctly depended on the image rule. Nonetheless, we still want to fix it for consistency.

* rootfs-cpio: add U-Boot image supportGravatar Arnout Vandecappelle2013-11-112-1/+33
| | | | | | | | | | | Adds U-Boot image support for cpio root filesystems. This allows you to use the bootm command in U-Boot to load the rootfs. It makes it possible to verify the CRC of the initramfs before booting the kernel.

* fs/common.mk: delay evaluation of variablesGravatar Arnout Vandecappelle (Essensium/Mind)2013-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | 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.

* fs/common: Create initial console deviceGravatar Markos Chandras2012-11-211-0/+2
| | | | | | | | | | | | | | | | | 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.

* cpio/initramfs: clarify their use in the help textGravatar Arnout Vandecappelle2012-11-071-3/+8
| | | | | | | | | | 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) <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* cpio: fix boot with dynamic /devGravatar Arnout 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.
