Comment 1 Norman Back 2019-04-06 10:50:16 UTC
Occurs when the mounted core system on an SSD. 
For mounted core system on HD reboot and shutdown work OK.

possible replacement for stock Gentoo's broken  /etc/init.d/dmeventd openrc init (right in the Gentoo script, it says, basically "# TODO: implement" :P)

For me this made a really, really big difference.  A lot bigger than I expected, straight from 'what on earth is wrong with this thing?!' to 'amazing!'

I have stuff in nonstandard boot-levels and injected additional dependencies from conf.d, however, so ... your mileage really will probably vary.  Also please make a backup before trying, no promises it won't eat your doctoral thesis or w/e.

Here's the latest and greatest, I think the original script developed a problem some months ago.... tbh can't really remember or be bothered to check.  What I do recall is that I made this change for what I thought at the time was a good reason :P
