1. Boot from an installation-os image.
2. cp /etc/issue /tmp
3. ls -l /tmp [observe that /tmp/issue exists]
4. mount -t ext4 /dev/sda1 /mnt
5. herd start cow-store /mnt
6. ls -l /tmp [observe that /tmp/issue has dissappeared]

Indeed, ‘cow-store’ bind-mounts /mnt/tmp (or whatever the target mount
point is) to /tmp to make sure we have enough disk space if we need to
build things. This was done in commit
0adabad72d58492f08975af0b6b837ebde32a51b in response to a bug report.
Is it a problem for the installer?
Thanks,
Ludo’.

It's not an insurmountable problem. But it is a bit annoying.
