macOS: re running install.sh fails (mktemp File exists)

[alejorrojas]

Hi!

I'm running the curl -fsSL https://raw.githubusercontent.com/dimensionalOS/dimos/main/scripts/install.sh | bash script on macOS (Tahoe 26.6.2) and the first run works, but if you run it again you get the following error:

mktemp: mktemp failed on /tmp/dimos-install.XXXXXX.sh: File exists
curl: (56) Failure writing output to destination

The problem is that the macOS mktemp only randomizes XXXXXX if it's the last part of the path. The .sh suffix makes a fixed filename, so following runs collide.

The patch is straightforward:

# /scripts/install.sh
-    TMPSCRIPT="$(mktemp /tmp/dimos-install.XXXXXX.sh)"
+    TMPSCRIPT="$(mktemp /tmp/dimos-install.XXXXXX)"

Also in the cleanup we can delete the temp install file created.
