--- Comment #24 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

I apologize beforehand since it's unrelated to the actual tmpfs problem but
since a few people here are claiming this feature to be used in conjunction
with rapid testing let me offer another potential solution.

--- snip ---
I also use ramfs a lot to test wine since it's much faster to create and
operate prefixes.

I admit prefixes backed by physical disks will always have inferior performance
but there might be an alternative.

I use btrfs subvolumes for prefixes for more than two years now, along with
'snapper' to ease snapshot management.
It allows me to snapshot/restore prefixes to any state in an instant using
btrfs builtin features.
This is especially useful for incremental testing and/or when intermediate
prefix states need to be captured/restored quickly.
In addition you get nifty features like builtin "diff" between arbitrary
snapshots. You can for example see which files changed in the prefix during
install or even which registry changes have been done (since the hives are text
files).

Regards
