SIDE NOTE: You will see references to nsupdate -k below. Note that in recent versions of this program, the option you want has changed to nsupdate -y. You will find an example of the new format later in this […]

FreeBSD now has zl4 compression for ZFS. But you must upgrade your pools to get it. If you try before upgrading, you’ll get: # zfs create -o recordsize=8k -o primarycache=metadata -o compress=lz4 system/usr/home/dan/pgsqlsql cannot create ‘system/usr/home/dan/pgsql’: pool must be upgraded to set this property or value So, let’s upgrade: # zpool upgrade -a This system supports ZFS pool feature flags. Successfully upgraded ‘system’ from version 28 to feature flags. Enabled the following features

In my work on FreshPorts, I’ve learned more than the average non-committer about the FreeBSD ports tree and its oddities. Just about everything learns about a port it gets from ‘make -V’. Even this method can be fraught with difficulty. In an attempt to get the fairest information possible, FreshPorts uses a chroot solution, first proposed by Ryan Steinmetz . Previous posts about this particular solution can be found in the FreshPorts blog.
