Subject: block: use /var/tmp instead of /tmp for -snapshot
X-Git-Tag: v2.0.0-rc0~44^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=69bef7931e8880c709556f8444938d8bb9a16118;p=thirdparty%2Fqemu.git

block: use /var/tmp instead of /tmp for -snapshot

If TMPDIR is not specified, the default was to use /tmp for the working
copy of the block devices.  Update this to /var/tmp instead, so systems
using tmp-on-tmpfs don't end up inadvertently using RAM for the block
device.
