Subject: tempfile: use /tmp for fallback-tempfiles
X-Git-Url: https://git.proxmox.com/?p=pve-common.git;a=commitdiff_plain;h=77b2b96ffcc973cb070325305ce2368fb6658f4a

tempfile: use /tmp for fallback-tempfiles

At this point we know it's not a tmpfs (as tmpfs definitely
supports O_TMPFILE), so /tmp makes more sense than /run as
default path.
