config DEFAULT_HOSTNAME
214
string "Default hostname"
217
This option determines the default system hostname before userspace
218
calls sethostname(2). The kernel traditionally uses "(none)" here,
219
but you may wish to use a different default here to make a minimal
220
system more usable with less configuration.

config VERSION_SIGNATURE
215
223
string "Arbitrary version signature"
609
bool "Namespace cgroup subsystem"
611
Provides a simple namespace cgroup subsystem to
612
provide hierarchical naming of sets of namespaces,
613
for instance virtual servers and checkpoint/restart

config CGROUP_FREEZER

bool "Freezer cgroup subsystem"

975
bool "Include all symbols in kallsyms"
977
976
depends on DEBUG_KERNEL && KALLSYMS
979
Normally kallsyms only contains the symbols of functions, for nicer
980
OOPS messages. Some debuggers can use kallsyms for other
981
symbols too: say Y here to include all symbols, if you need them
982
and you don't care about adding 300k to the size of your kernel.
986
config KALLSYMS_EXTRA_PASS
987
bool "Do an extra kallsyms pass"
990
If kallsyms is not working correctly, the build will fail with
991
inconsistent kallsyms data. If that occurs, log a bug report and
992
turn on KALLSYMS_EXTRA_PASS which should result in a stable build.
993
Always say N here unless you find a bug in kallsyms, which must be
994
reported. KALLSYMS_EXTRA_PASS is only a temporary workaround while
995
you wait for kallsyms to be fixed.
978
Normally kallsyms only contains the symbols of functions for nicer
979
OOPS messages and backtraces (i.e., symbols from the text and inittext
980
sections). This is sufficient for most cases. And only in very rare
981
cases (e.g., when a debugger is used) all symbols are required (e.g.,
982
names of variables from the data sections, etc).
984
This option makes sure that all symbols are loaded into the kernel
985
image (i.e., symbols from all sections) in cost of increased kernel
986
size (depending on the kernel configuration, it may be 300KiB or
987
something like this).
989
Say N unless you really need all symbols.
