The maximum expected number oC simultaneously active user on this system is number.
This number is used to size several system data structures.
o{Jtlons opt/ist
Compile the listed options into the system. Options in this list are separated by commas.
There is a list of options that you may specify in the generic makefile. A line oC the form
"options FUNNY,HAHA" yields -DFUNNY -DHAHA to the C compiler. An option may be
given a value, by Collowing its name with
"="
then the value enclosed in (double) quotes.
None of the standard options use such a value.
eonfl. sl/sname confio_clauses ...
Generate a system with name sllsname and configuration as specified in config-clauses. The
8118name is used to name the resultant binary image and per-system swap configuration files.
The config_clauses indicate the location for the root file system, one or more disk partitions
for swapping and paging, a disk partition to which system dumps should be made, and a
disk partition on which execve argument lists should be constructed. All but the root device
specification may be omitted, config will fill them in with deCault values as described below.
root A root device specification is of the form root on xll0d. It a specific partition is
omitted -
for example, if only root on xyO is specified -
the "a" partition is
assumed. When a generic system is being built, no root specification should be
given; the root device will be defined at boot time by prompting the console.
swap Swap device specifications have two possible forms. It a generic swap configuration
is required, the clause swap generic should be specifed. Otherwise, if a single par-
tition is to be used for swapping, one may specify 8wap on
X1l06.
If multiple parti-
tions are to be interleaved one should specify something of the form swap on
xyO
and xl/1 and xl/1g. If no swap specification is given, config assumes swapping
should be done on the "b" partition of the root device. Swapping areas may be
almost any size and multiple swap partitions of varying size may be interleaved.
Partitions used Cor swapping are sized at boot time by the system; to override
dynamic sizing of a swap area the number of sectors in the swap area can be
specified in the con fig file. For example, 8wap on
%1106
size
99999
would configure a
swap partition with 99999 sectors.
arls The partition to be used for argument list processing may be specified with a clause
of the form args on xI/lb. It no argument device is specified, the first swap parti-
tion specified is used. If a device is specified without a particular partition, the "b"
partition is assumed. If a generic system is being built, no argument device should
be specified; the argument device will be assigned to the swap device dynamically
configured at boot time.
dumps The loca.tion to which system dumps are sent may be specified with a clause of the
form dumps on x1/1. If no dump device is specified, the first swap partition
specified is used. If a device is specified without a particular partition, the "b" par-
tition is assumed. It a generic configuration is to be built, no dump device should
be specified; the dump device will be assigned to the swap device dynamically
configured at boot time.
Dumps are placed at the end of the partition specified. Their size and location is
recorded in global kernel variables dump8ize and dumplo, respectively, for use by
8avecore(8).
Device names specified in configuration clauses are mapped to block device major numbers
with a file ISIJsl co nIl devices. machin e, where machine is the machine type previously
specified in the configuration file. H a device name to block device major number mapping
must be overridden, a device specification may be given in the form
major
