This is the maximum number of characters (including NUL characters) allowed in
the argument and environment strings passed to an exec system call.
This can be increased to allow larger argument lists.
FPKIND
Type of floating-point support:
``0''=auto-detect, ``1''=software emulator,
``2''=Intel 287 coprocessor, ``3''=Intel 387 coprocessor.
INITFILE
Specifies the file to use as input to /sbin/init
(default is /etc/inittab).
MAXLINK
Specifies the maximum number of links (directory entries)
permitted in a single directory.
Do not attempt to increase this value beyond ``32767''.
NULLPTR
Controls the default state of the null pointer workaround and
whether logging should occur.
When the value is ``0'', the workaround is disabled by default,
and logging is disabled;
when the value is ``1'', the workaround is enabled by default,
and logging is disabled;
when the value if ``2'', the workaround is enabled by default,
and logging is enabled.
When the workaround is enabled [either by default or through the
nullptr(1)
command], null pointer reads return zero
instead of faulting with SIGSEGV.
When logging is enabled and the workaround is enabled for a process,
the first time an executable program in that process
reads a null pointer, a message is sent to the console.
PRFMAX
Maximum number of kernel symbols for which the kernel profiler
has space allocated.
PROCTLLID
Specifies the Level ID when you use MAC
(Mandatory Access Control) for the control file in the processor filesystem.
PUTBUFSZ
Specifies the size of a circular buffer, putbuf,
that is used to contain a copy of the last PUTBUFSZ
characters written to the console by the operating system.
The contents of putbuf can be viewed using the
crash(1M)
command panic option,
or from kdb using putbufnumber of charactersdump.
SANITYCLK
Enable sanity clock on machines that support this feature.
SHLBMAX
Specifies the maximum number of static shared libraries
that can be attached to a process at one time.
SYSDUMP_SELECTIVE
This parameter controls the size and type of information stored in
a system memory dump.
If the value is ``0'', then both kernel and
user mapped memory are dumped (assuming the dump slice is large enough).
If the value is ``1'', then only kernel mapped memory is dumped.
If the value is ``2'', only a selected portion of kernel mapped
memory pages are dumped.
The
crash(1M)
command is used to examine the dumped system images.
SYSDUMP_ABORT_VERIFY
If set to ``1'', a prompt is issued which requires you
to enter ``yes'' (case insensitive) to abort a dump.
Pressing <Enter> instead of entering ``yes''
causes dump processing to continue.
If set to ``0'', any key pressed during the dump processing will
abort the dump.
USER_RDPMC
When non-zero, the user can use the rdpmc instruction, if available.
USER_RDTSC
When non-zero, the user can use the rdtsc instruction, if available.
