3 # Description: FreeBSD comes with the following script that is run
4 # weekly as part of its periodic weekly security scripts.
5 # However, their version of the script does NOT ignore
6 # .zfs/snapshot directories. On a system with limited
7 # resources, this can lead to a "kmem_map too small"
8 # kernel panic when this script runs. Somehow, ZFS
9 # kernel memory usage explodes when performing recursive
10 # find operations on .zfs snapshot locations. This
11 # is the modified version of that script, which excludes
12 # searching in .zfs snapshot directories.
