Thanks, Robert . . .

I was grokking your suggestion till I got to the Ubuntu notes. The only file in the sysctl.d on Devuan is the README.sysctl. And grep couldn't find 10-magic-sysrq.conf so I just put the needed line into sysctl.conf. I haven't tested it but reisub/o should be good to go now.

Cheers!
