NAME

adjust_kernel_headers - select version of kernel headers

SYNOPSIS

adjust_kernel_headers [--list | --auto | --first | kernel-version]

DESCRIPTION

adjust_kernel_headers maintains symbolic links which are used to select one of the available versions of kernel headers as the default kernel headers for the system.

Initially kernel headers selection is performed in the automatic mode. In this mode, when adjust_kernel_headers is called without parameters, it selects headers which match the running kernel; if such headers are not available, headers from the glibc-kernheaders package will be selected. This adjustment is performed by the kheaders service at every system startup, and also by installation scripts of packages with kernel headers.

If such automatic adjustment is not desired, the system administrator may switch kernel headers selection to the manual mode. In this mode adjust_kernel_headers called without parameters will not select a different version of headers, unless the manually selected version is no longer available (in which case it will switch to the automatic mode).
