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: Add BR2_TARGET_ROOTFS_EXT2_MKFS_OPTIONS option

2017-07-09T13:35:42+00:00

This option lets the user specify mke2fs options and/or ext2/3/4 features. Signed-off-by: Sébastien Szymanski Signed-off-by: Samuel Martin Cc: "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.

Globally replace $(HOST_DIR)/usr/sbin with $(HOST_DIR)/sbin

2017-07-05T13:19:44+00:00

Since things are no longer installed in $(HOST_DIR)/usr, the callers should also not refer to it. This is a mechanical change with git grep -l '$(HOST_DIR)/usr/sbin' | xargs sed -i 's%$(HOST_DIR)/usr/sbin%$(HOST_DIR)/sbin%g' Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni

fs/ext2: use mkfs to generate rootfs image

2017-07-04T22:39:38+00:00

mkfs is now capable of generating rootfs images. Use mkfs instead of genext2fs. If not set, we now let mkfs calculate the block size and the number of inodes needed. This change also adjusts the options to meet those of mkfs. Notes: * Passing a null inode number to mkfs triggers its automatic calculation. * Passing a fs-size with no unit suffix to mkfs is interpreted as using 1K block size.

fs/ext2: deprecate BR2_TARGET_ROOTFS_EXT2_EXTRA_INODES option

2017-07-04T22:35:00+00:00

Soon, the ext{2,3,4} rootfs image will no longer be generated with genext2fs, but using mke2fs instead which has no support for the extra inode number option. So, deprecate the BR2_TARGET_ROOTFS_EXT2_EXTRA_INODES option and recommend, in lieu, to set the total inode number, taking account of the extra ones if needed.

package/mke2img: add option to specify block size

2017-07-04T06:50:40+00:00

ext filesystems can use a block size of 1024, 2048, or 4096 bytes, the former being interesting to store small files, while the latter being more intersting to store bigger files. So far, we were using the default, which was to use a 1024-byte block. Continue doing so (for now...). Signed-off-by: "Yann E. MORIN" Signed-off-by: Samuel Martin Signed-off-by: Thomas Petazzoni

fs/ext2: simplify code

No option is conditional anymore, so just collate them into a single assignment. Signed-off-by: "Yann E. MORIN" Signed-off-by: Samuel Martin Signed-off-by: Thomas Petazzoni

fs/ext2: allow reserving zero block for root

2017-07-04T06:47:57+00:00

The previous default, zero, just meant "use the default value of the filesystem generator", which happened to be 5% (the traditional value for all ext-creating tools we've ever seen). So, change the new default accordingly to 5%. Signed-off-by: "Yann E. MORIN" Signed-off-by: Samuel Martin Signed-off-by: Thomas Petazzoni
