Sometimes makechrootpkg fails with:

This shouldn't cause the whole script to fail, so let's tolerate a missing pipe
As a matter of curiosity, when does this happen? I don't recall offhand seeing it.
I'm not saying it's fundamentally wrong to make this change, but I wouldn't have expected this to be a problem.

If we just checked using [[ -p namedpipe ]] then it seems like the window for a TOCTOU is pretty narrow...
Aside for which, if we've reached this point then we're already erroring out, so -f would only silence a warning, not make anything succeed. So this should not be what is causing the whole script to fail.

I'm curious under what situation we could tee to a file, wait until tee exits, and then try but fail to delete the file.
IIRC the only times we use run_function() are inside run_function_safe() which sets up errexit, so if this fails then that would explain why the script would abort, but I don't get how the file is supposed to disappear in the first place.
I don't understand this either... Note that there is no evidence of this occurring when running makepkg directly. Only under the Arch devtools package. I get the feeling this is papering over an issue in devtools, and am reluctant to pull the patch unless there information to say otherwise. Allan
