Thanks!
Still... maybe it is a starting point for thinking about the problem.
Yes, you're right,
Throwing a few ideas into the mix - shoot them down if they seem too
outrageous :-)
1) Can we apply xattrs to devices in /dev?
2) Does xattrs lock out root?
Okay, this won't necessarily hide component devices, but if assembling
an array (optionally) applies xattrs to them, and makes them writeable
*only* by user "mdadm", then that will help prevent a load of damage. Of
course, that doesn't protect a partition against be overwritten by a
write to the underlying drive, but that's a whole 'nother can of worms...
And of course, the question is will this lock out the operations we
don't want, while allowing stuff that we do ...
Provided xattrs does lock out root from user space, this looks to me to
be the obvious route to try to go down, but what do I know?
Cheers,
Wol
