Infrastructure Software

I am running Sol 10 11/06 on a Sun Blade. I installed Sol 10 from DVD a few months ago, making my / partition 12GB in size. /var is not a separate partition. Sun Studio 11 was also installed. I have installed all available patches using Sun Update Manager. Since installation, my / partition has filled up with more than 860 MB of data, none of it from me. I assume that all that space is being used up by superseded versions of installed patches. Does this seem normal? Am I supposed to put up with this until the disk fills up with old, unused patches? /var/adm is ok in terms of the wtmpx file being small (678k). /tmp is clean. I shutdown the computer whenever I am not using it, so MANY reboots have occurred. Here is my df -h:

df -h
Filesystem size used avail capacity Mounted on
/dev/dsk/c0t0d0s0 12G 6.3G 5.4G 55% /
/devices 0K 0K 0K 0% /devices

swap 5.2G 1.6M 5.2G 1% /tmp

/dev/dsk/c0t2d0s7 37G 14G 22G 40% /storage1
/dev/dsk/c0t0d0s3 19G 1000M 18G 6% /storage2
/dev/dsk/c0t0d0s7 1.9G 687M 1.2G 36% /export/home

Is there somewhere else I should look for large log/error files, or is the space usage on / normal? Should I back out all the unused patches (I am very, very reluctant to waste time on that)?


Thank you.......
