Sometimes I will run two snapcraft cleanbuild at the same time, usually because one is very long running, and while I wait for it to finish, I want to do something else. This breaks.
alan@hal:~$ snapcraft --version
snapcraft, version 2.33+git39.f820733
alan@hal:~$ lxd --version
2.16
Steps to reproduce
mkdir foo bar
cd foo
snapcraft init
cd ../bar
snapcraft init
Then in two terminals, run snapcraft cleanbuild a few seconds apart, one in ./foo and one in ./bar. One (the first one to be started) will finish successfully. The second will fail with the following issue:-

Looks to me like the “snapcraft.tmp” directory should have a generated name, not a static one.
