Divvy a hard disk

Personally, I would use MB and stay away from blocks. Also, Those things you quoted are only guidelines and minimums.
In my environment, we do it like this. Remember these are only one way to do this. Also, everything depends on the OS flavor and whatever you have running on the box and how big of a system it is.
/ .................250MB.
/var ............1600MB. ( 1.6GB)
/usr.............1600MB.
/opt.............1000MB.
/home..........500MB to 1.5GB
/tmp.............2000MB to 4000MB ( 2GB to 4GB) Depends on demands of Application running on box. Link /var/tmp to /tmp so /var doens't fill up.
That adds up to 6.5GB to 8GB, which leaves 2GB to 3.5 for other things.
primary swap ( at least 2x to 3x of RAM) and 2ndary swap for OS same size as primary swap.
also, have a root swap in the root volume and another secondary swap for everything else.
dump space ( at least 30% to 50% of RAM)
crash space ( same as dump different place) Some OS are configured to use swap space as crash for system crashes. I would use the secondary swap, not root swap.
Hope this Helps you.

info(4) Kernel Interfaces Manual info(4) NAME
info - diskless client configuration information file DESCRIPTION
The file is a POSIX shell sourceable file which contains parameter definitions used at boot time. Typically, it will be an empty file and default values will be used for all parameters. Following is the list of parameters which can be defined in the file: Specifies the IP address of the client's private root server. If this is not specified, the client's private root server defaults to the boot server. Specifies the pathname to the client's private root on the private root server. If this is not specified, the client's private root path defaults to Specifies the NFS mount options to mount the client's private root from the private root server. If this is not specified, the mount options default to Specifies the NFS mount options to mount the client's directory from the boot server. If this is not specified, the mount options default to Specifies whether NFS should be configured as primary swap. (NOTE: In order to swap to NFS, a diskless kernel must be configured with tunable parameter set to 1.) If a diskless machine has a local swap disk and swap to NFS is not desired, the parameter should be set to the value of 1 and the diskless kernel should be configured without setting to 1. If this parameter is not specified in the file and the kernel tunable parameter is set to 1, then NFS will be configured as primary swap. If not set, this parameter defaults to a value of 1, and results in the removal of all swapfiles above the configured swap minimum (swap is specified in the client's when a disk- less client boots. This ensures that extraneous swapfiles at boot time are removed, thus freeing disk space. If is set to 0 in the file, removal of extra swapfiles is disabled. This may result in faster boot times due to the time savings in creating additional swap files. The file resides in the same directory as the client's kernel () on the boot server and is retrieved at boot time using command. By default, when a diskless client is created, an empty file is placed in the client's kernel directory. This ensures that all parameters revert to their default values (see above). If the file is not present, this is an error. EXAMPLES
