ZFS Bootloader for root-on-ZFS systems with support for snapshots and native full disk encryption

Project mention: Bash Debugging | news.ycombinator.com | 2024-03-01

We use a couple nice home-grown functions in ZFSBootMenu to help debug things. We have a zdebug logging function that's peppered liberally throughout the code base - https://github.com/zbm-dev/zfsbootmenu/blob/master/zfsbootme...
Hitting ctrl-t on our main menu will, when booting with debug logging enabled, show a screen like this: https://imgur.com/Ge75zkP
We also have a flamegraph profiling mechanism that can be enabled with https://github.com/zbm-dev/zfsbootmenu/blob/master/zfsbootme... . That will dump data to a serial port, which when re-assembled, can be used to produce a graph like https://raw.githubusercontent.com/zbm-dev/zfsbootmenu/master...
Bash is suprisingly flexible.
