Image building challenges on macOS

[weikengchen]

I tried to build the image and take the measurements on my macOS today.

macOS version: Tahoe 26.0.1
Lima version: 2.0.1 (recent)

Here are two errors that I encountered and the solution, but I am glad that I eventually fixed them and got the measurement.

1. Lima has a fatal error mounts[0].location must be an absolute path, found "."

This seems to be due to

mounts: 
    - location: "." # cwd of `limactl start` command"

I fixed it by replacing the location with the pwd of the root directory of this repository.

2. "make build" may fail in "/work/finalize" due to "PROFILES" not set

Note that debloat.sh will check "$PROFILES". If this variable is not present, it may fail. This is related to a recent commit @c5eec3efed85f4546b34417ac6794037db99491d

if [[ ! "$PROFILES" == *"devtools"* ]]; then
    debloat_paths+=(
        "/usr/share/bash-completion"
    )
fi

I fixed it by using "make build-dev" because it would supply "--profile=devtools" so at least this variable is not empty. But I think maybe the Makefile should supply something for "make build"

For building the buildernet, I think I just don't have a working env.json (and it would fail in the curl step).

In case a yaml file update is happening, this warning could also be handled:

"WARN[0000] Both top-level 'rosetta' and 'vmOpts.vz.rosetta' are configured. Using vmOpts.vz.rosetta. Top-level 'rosetta' is deprecated."
