Space on root partition

[Chip Camden]

When partitioning the drive, I took the defaults -- which seems to create
a root partition that's too small.  I'm at 59% usage, and every time I
install a new kernel I have to rm /boot/kernel.old to get it to go.

Two questions:

1. Is there an easy way to resize partitions?
2. Is there anything in root I could safely symlink off to another partition?

Here's a df:

Filesystem  1K-blocks     Used     Avail Capacity  Mounted on
/dev/ad4s1a    507630   273388    193632    59%    /
devfs               1        1         0   100%    /dev
/dev/ad4s1e    507630       18    467002     0%    /tmp
/dev/ad4s1f 463086528 21941374 404098232     5%    /usr
/dev/ad4s1d   4848462   201194   4259392     5%    /var

and here's du -x /:

2	/.snap

Any help much appreciated.
