Thanks Mike. I tried that but there were no log messages. But then
it dawned on me what the cause of the problem (with custom kernel) was :
systemd was reporting this on the console:
Failed to mount /dev: No such device
This made no sense to me until I checked what the errno corresponding to
this and what causes that errno from a mount() :
ENODEV filesystemtype not configured in the kernel.
So that was my "misconfiguration". Mentioning it in case anyone
else hits this and is baffled.
Also - just a thought - maybe systemd should treat this as a warning
rather than a showstopper and try to carry on (i.e. use the existing
/dev structure); in my case it would (I believe) have come up ok plus
or minus a few trivial parts. And, yes - now I see devtmpfs is
stated in the README REQUIREMENTS :-X
Cheers, John
