Mixed feelings today.
My #MacBookPro (late 2008) running #OSX #ElCapitan wasn't "allowed" to execute a set of terminal tasks due to lack of support, both from the mother company and #homebrew community :flan_disappointed:​ .
On the positive side my #ThinkpadT43p (2005) running #FreeBSD12.1 pulled it through :flan_hurrah:​ .

I wanted to try #Gnome3 on my #ThinkPadT43p 2005 - I know I know... too much for the old loyal servant...
I created a #bootenvironment as described by @mwlucas and installed the packages as per the #freeBSDhandbook. The old servant couldn't handle it... so I wanted to restore my system from the boot environment. After beadm activate and reboot everything went back to the previous state... except hidden files in my home directory...
Is this some kind of a setting in the #ZFS #bootenvironment ???

Excited setting up the last IBM #ThinkpadT43p running FreeBSD 12.1 i386 with zfs. I purchased the computer in 2005. It served me well as a #DesignMachine during my masters and as my first production computer. It worked hard on architectural 3D design and animation in Maya. 2020 brings a new chapter in its life with the support of #FreeBSD.
