value less than 1 is specified, the script defaults the
variable to 1 and writes a warning message in the
package control script log file.
CONCURRENT_FSCK_OPERATIONS
Specifies the number of concurrent fsck commands to
allow during package startup. The default is 1. Setting
this variable to a higher value may improve
performance when checking a large number of file
systems. If a value less than 1 is specified, the script
defaults the variable to 1 and writes a warning
message in the package control script log file.
CONCURRENT_MOUNT_OPERATIONS
Specifies the number of mounts and umounts to allow
during package startup or shutdown. The default is 1.
Setting this variable to a higher value may improve
performance while mounting or unmounting a large
number of file systems. If a value less than 1 is
specified, the script defaults the variable to 1 and
writes a warning message in the package control script
log file.
IP Addresses and SUBNETs
These are the IP addresses by which a package is
mapped to a LAN card. Indicate the IP addresses and
subnets for each IP address you want to add to an
interface card. Package IP addresses may be either
IPv4 addresses or IPv6 addresses. For more details of
IPv6 address format, see the Appendix , “IPv6 Address
Types,” on page 468
In the package control script file, these variables are
entered in pairs. An IPv4 example is
IP[0]=192.10.25.12 and SUBNET[0]=192.10.25.0.
(In this case the subnet mask is 255.255.255.0.) An
IPv6 examples is IP[0]=2001::3 and
SUBNET[0]=2001::/64. (In this case the subnet mask
is ffff:ffff:ffff:ffff::.)
