Use of /tmp dir when doing snapshot

[Vaclav Adamec]

Hi,

 is there any way how to override /tmp usage during snapshot creation ? using v0.8.1

$ consul snapshot save backup.snap

# create temporary file in /tmp/snapshotXXXXXXXX

# than rename/mv to final file 'backup.snap'

Based on GO TempDir https://golang.org/pkg/os/#TempDir this should
work, but seems to be ignored (still writing to /tmp):

$ export TMPDIR='/var/tmp' consul snapshot save backup.snap

Hi,

Currently there's not a way to control this. The snapshots you run
through the API use the same code path that Consul uses internally
when it's snapshotting and truncating the Raft log, so this would be
kind of a big change to split out, unfortunately.

Via TMP_DIR variable in systemd unit for consul it works (need reload of systemd and restart of Consul but better than nothing)

Ah I didn't realize that Go would respect that - thanks for the update.
