Look which bits are different - digits 24, 53-56 in both cases.
You could try copying the file to /tmp (ie swap/ram) and do a continues loop of

disk drives (eg boot).

zfs set reservation=100GB dataset/name
That will reserve 100 GB of space for the dataset, and will make that

That doesn't make any sense to me ...
How does that allow subversionuser to use the space, and block joeuser from
using it?

The question is how to create reservations for users.
One way to create a reservation for a user is to create a quota for everyone
else, but that's a little less manageable, so a reservation per-user would
