Having to have access to reinstall my laptop, I’m putting this up. Mirrored Encrypted ZFS configuration.

Verify actual disks by doing ls -l on the $DISK Variable. May switch between reboots. 

DISK1=/dev/disk/by-id/nvme-CT4000P3PSSD8_2252E6966FC3

For a non-mirrored boot configuration. Making the partitions size match to ZFS doesn't complain on the mirror creation.

Our 2024-2025 school year picked up on the road, continuing our travels around the country in Yellowstone National Park. From there, we traveled to many other sites on our way back to Florida, to include:

Grand Tetons NP
Little Big Horn National Monument
Fort Union Trading Post
Theodore Roosevelt National Park
Knife River Historic Site
Devils Tower
Wind Cave National Park
Mt. Rushmore
Jewel Cave National Monument
Homestake Gold Mine
Minuteman Missile NHS
Badlands National Park
Agate fossil Beds NM
Scotts Bluff NM
Fort Laramie & Guernsey Wagon Ruts
Homestead NHP
Brown V. Board of Education NHS
Fort Larned NHS
Tallgrass Prairie NP
Strataca – Kansas underground salt museum / salt mine
Chickamauga & Chattanooga NMP
Russel Cave NM
Little River Canyon Nat. Preserve

Arriving back in Florida, we took a break for Thanksgiving and started to get back into the book work.

I logged their work on a blog post (pdf file) from December to January. After January, we switched to homeschool sheets where they documented what they did for that day.

From November to March we were living in the RV, conducting home school in the RV or outside on the patio. After April on we moved back into our house. Due to the efforts required with the move, we stopped most book work activities in April and through the summer.

Over the summer the three attended several summer camps with the Scouts. Jarek earned over 14 merit badges this summer in a variety of subjects and activities. Jarek worked on Saxon math 7/8 and the more advanced writing program which introduced outlines in preparation for writing papers. He has done very well with his reading, reading numerous book. He also took violin lessons and scored well on his Theory exam. I’ve looked for his results for his recorded performance, but I appear to not have them.
