One for those running #ZFS on #Linux systems. I realise that you can't have hibernate aka suspend to disk on a swap in the encrypted zpool but if you don't use hibernation then is it OK to use swap using the likes of the command example below to set it up in the encrypted pool?

I should point out that I'm thinking of switching from my current Void Linux luks lvm setup to Void with fully encrypted zpool and zfsbootmenu on my ThinkPad P14s AMD Gen 1which has 16Gb ram that I may upgrade to 40Gb. It also has a 1Tb nvme.

zfs create -V "${v_swap_size}G" -b "$(getconf PAGESIZE)" -o compression=zle -o logbias=throughput -o sync=always -o primarycache=metadata -o secondarycache=none -o com.sun:auto-snapshot=false "$v_rpool_name/swap"

It’s 512GB of ssd cache plus 128GB of ram, so for now that’s been enough

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
