[amongst others] /bin/sh: 1: zfs: not found suggests the need for /usr/sbin/zfs It seems reasonable that /usr/sbin/* should be available to root crontab. Why isn't root's $PATH available to root crontab? ie. including the link /sbin -> /usr/sbin? > "All your crontab entries run in parallel. OK thanks.

I was of the impression (which I think it is fair to say has been created) that systemd had done away with /etc/rc.local, and crontab @reboot is much simpler than systemd units and whatever dependencies there may be. > Figure out whether your commands are allowed to run in parallel [...] They are not. > If they're not, use a *script* [...] With /usr/bin/zfs, that's working, thank you.
