Installation Fails if /var Has Just Minimum or Recommended Disk Space (6873975)

On systems with low memory, installation might fail if either / or /var have just minimum or recommended disk sizes. The following error message is displayed:

Creating boot_archive for /a
updating /a/platform/sun4u/boot_archive
15+0 records in
15+0 records out
cat: write error: No space left on device

Workaround: Increase the size of /var to at least 300 Mbytes on low memory systems.
