9# You're probably looking here thinking you need to create some new copy
10# of linux-libc-headers since you have your own custom kernel. To put
11# this simply, you DO NOT.
12#
13# Why? These headers are used to build the libc. If you customise the
14# headers you are customising the libc and the libc becomes machine
15# specific. Most people do not add custom libc extensions to the kernel
16# and have a machine specific libc.
17#
18# But you have some kernel headers you need for some driver? That is fine
19# but get them from STAGING_KERNEL_DIR where the kernel installs itself.
20# This will make the package using them machine specific but this is much
21# better than having a maching specific C library. This does mean your
22# recipe needs a DEPENDS += "virtual/kernel" but again, that is fine and
23# makes total sense.
24#
25# There can also be a case where your kernel extremely old and you want
26# an older libc ABI for that old kernel. The headers installed by this
27# recipe should still be a standard mainline kernel, not your own custom
28# one.
