xtool setup hangs on "Extracting XIP" if /tmp is full/doesn't have enough space

[zImPatrick]

When running xtool setup and entering a path to a valid SDK, xtool can just hang on Extracting XIP (in my case, at 75%) when /tmp is full/nearly full.

Arch Linux, for example, mounts /tmp to tmpfs and has a maximum size of half of my available memory. On my PC with 32 GB of memory, this wasn't an issue and the installation proceeded without any issues. On my laptop with 12 GBs of available memory however, the installer just hung and gave no further information.

My quick and hacky workaround was to mount /tmp (or /tmp/DarwinSDKBuild) to some other location using a bind mount so that disk space is no problem.

Same issue on Ubuntu 25.04. I think it should unzip to ~/.config/xtool, not /tmp...

At this stage, it is possible to try to modify the size of tmp. My test shows that it is feasible

to fix this, i just did the same sort of hacky workaround and temporarily bind mounted tmp to a folder in my home directory

I get the same on Ubuntu 25.04.

I ran sudo mount -o remount,size=15G /tmp, it got me further but the install then quit later in the process due to not enough space.

I have 16GB of RAM on my laptop.

This issue should sort-of be fixed with #147. Once that PR lands, you can do export XTL_TMPDIR=/var/tmp (or any path of your choosing) to decide where xtool stores temporary files. We still default to $TMPDIR or NSTemporaryDirectory() (aka /tmp on Linux), as I don't know of a portable way to ask for a "temp directory not backed by tmpfs" but open to suggestions.
