37 Through it you can specify the kernel to be booted,
38 parameters to be passed to it,

63 some settings are treated in a special fashion.
64 Also, the behavior of some settings is defined by the setting's suffix;
65 the prefix identifies which module the setting controls.
67 The general parsing rules are:
70 Spaces and empty lines are ignored.
74 sign will mark the remainder of the line as a comment.
76 Only one setting can be present on each line.
79 All settings have the following format:
83 This assigns value to a local variable.
84 If variable is in a list of known kernel environment variables or
86 it is also assigned to the kernel environment variable of the given name.
88 The settings that receive special treatment are listed below.
89 Settings beginning with
