The rootfs*
classes support creating
the root filesystem for an image and consist of the following classes:
The rootfs-postcommands
class, which
defines filesystem post-processing functions for image recipes.
The rootfs_deb
class, which supports
creation of root filesystems for images built using
.deb
packages.
The rootfs_rpm
class, which supports
creation of root filesystems for images built using
.rpm
packages.
The rootfs_ipk
class, which supports
creation of root filesystems for images built using
.ipk
packages.
The rootfsdebugfiles
class, which installs
additional files found on the build host directly into the
root filesystem.
The root filesystem is created from packages using one of the
rootfs*.bbclass
files as determined by the
PACKAGE_CLASSES
variable.
For information on how root filesystem images are created, see the "Image Generation" section in the Yocto Project Overview and Concepts Manual.
