Diskless Booting Can't Set /var in mfs larger than 4MB

[Bill Tillman]

I have a diskless workstation booting nicely but for some reason I cannot get the /var directory to set larger than 4MB. The docs I read said edit /pxeroot/conf/base/etc/fstab like this:

# Device                Mountpoint      FStype  Options               Dump    Pass#
md         /var                       mfs          -s=30m,rw        0             0
md                              /tmp                      mfs          -s=30m,rw        0             0
proc                         /proc                     procfs                rw               0             0

When I do this the /tmp directory sets up in mds at 30MB in size. But /var always comes up at only 4MB in size. Can anyone tell me how to adjust the size of /var in a diskless setup?
