fs/iso9660: really create initrd temp dir

2017-08-15T15:50:11+00:00

In case we're using an initrd, we create an empty "root" directory that will contain only the bootloader stuff, not the actual root filesystem, because it is in an initrd (standalone or initramfs). We have to ensure that the directory is empty before assembling the filesystem (to avoid any file lingering from a previous run, like the sequence "make; make"). So we first remove it before we create it, so that on each build (especially not-from-scratch builds) we get the exact expected content without any leftover. However, the macro responsible for that, although defined since 7080eef9, was never called. Fix that by registering it as a pre-gen hook. Note: the directory need not be created, as there are quite a few "install -D" commands that ensure it is created. Yet, we prefer to create it explicitly to avoid any confusion.

fs: add pre- and post-command hooks

2017-08-02T18:58:27+00:00

In some cases, the directory structure we want in the filesystem is not exactly what we have in target/ For example, when systemd is used on a read-only rootfs, /var must be a tmpfs. However, we may have packages that install stuff in there, and set important rights (via the permission-table). So, at build time, we need /var to be a symlink to the remanent location (/usr/share/factory) while at runtime we need /var to be a directory. One option would have been to have /var as a real directory even during build time, and in a target-finalize hook, move everything out of there and into the "factory" location. However, that's not possible because it's too early: some packages may want to set ownership and/or acces rights on directories or files in /var, and this is only done in the fakeroot script, which is called only later during the assembling of the filesystem images. Also, there would have been no way to undo the tweak (i.e. we need to restore the /var symlink so that subsequent builds continue to work) if it were done as a target-finalize hook. The only solution is to allow packages to register pre- and post-hooks that are called right before and right after the rootfs commands are executed, and inside in the fakeroot script. We can however not re-use the BR2_ROOTFS_POST_FAKEROOT_SCRIPT feature either because it is done before the filesystem command, but there is nothing that is done after. Also, we don't want to add to, and modify a user-supplied variable. So, we introduce two new variables that packages can set to add the commands they need to run to tweak the filesystem right at the last moment. Those hooks are not documented on-purpose; they are probably going to only ever be used by systemd. Signed-off-by: "Yann E.

fs/ext2: hint about setting the filesystem size on error

2017-07-25T22:53:05+00:00

Since we now request that the user sets the exact size of the ext2/3/4 filesystem, we've had quite a few users wondering what was going on when they enable too much and the default 60M are no longer enough. When mkfs.ext2 fails, print a hint that the user should check the size setting. Signed-off-by: "Yann E.

fs/ext2: rename BR2_TARGET_ROOTFS_EXT2_BLOCKS to BR2_TARGET_ROOTFS_EXT2_SIZE

2017-07-09T13:35:30+00:00

This change deprecates the ext2/3/4 rootfs size in blocks symbol in favor of one that mimic the fs-size argument behavior of mkfs (i.e. size in a human readable format accepting k, m, g or t suffix or their upper-case variants). This change also updates the defconfigs that used to set BR2_TARGET_ROOTFS_EXT2_BLOCKS symbol.
