Disk and file system partitions question

[Paul Moore]

I've just initialised the 140 Mbyte hard disk on my ISC-based system, as
follows:

       DOS Partition
       UNIX Parition:
          /
          /usr
          /usr2

and then spent 4 hours copying software into the root and /usr file systems.
While loading the last piece of software into /usr, I got the message that
there wasn't enough space left in /usr. Definitely a case of Murphy's Law
raising its ugly head!

Without re-initialising the disk and re-loading the software already loaded:

1. Can I increase the size of /usr at the expense of /usr2?

2. Can I vary the realtive sizes of the DOS and UNIX partitions?

Thanks, PPM
