Copies files that are to be packaged into the holding area
${
D
}
.
This task runs with the current working directory set to
${
B
}
,
which is the compilation directory.
The do_install
task, as well as other tasks
that either directly or indirectly depend on the installed files
(e.g.
do_package
,
do_package_write_*
,
and
do_rootfs
),
run under
fakeroot.
When installing files, be careful not to set the owner and
group IDs of the installed files to unintended values.
Some methods of copying files, notably when using the
recursive cp
command, can preserve the
UID and/or GID of the original file, which is usually not
what you want.
The
host-user-contaminated
QA check checks for files that probably have the wrong
ownership.
Safe methods for installing files include the following:
The install
utility.
This utility is the preferred method.
The cp
command with the
"--no-preserve=ownership" option.
The tar
command with the
"--no-same-owner" option.
See the bin_package.bbclass
file in the meta/classes
directory of the
Source Directory
for an example.
