Builds a full dev workstation from a bare Arch Linux install. https://git.cjennings.net/archsetup/atom?h=main 2026-07-20T20:38:36+00:00 2026-07-20T20:38:36+00:00 Craig Jennings c@cjennings.net 2026-07-20T20:38:36+00:00 urn:sha1:aef074f711566159d200021f7133f7713f2aaf8d `df /` wraps to two lines when the root device name is long -- a device-mapper or live-ISO root -- so `awk 'NR==2 {print $4}'` read the wrapped device line, found an empty Available field, and aborted a valid install with "Insufficient disk space." `df -P` forces POSIX single-line output. The gate now compares available KB against the minimum in KB rather than truncating to GB first, which rejected a disk sitting just under a whole-GB boundary. Non-numeric df output falls back to zero so a malformed read aborts loudly instead of crashing the arithmetic test. Extracted the logic into check_disk_space so it can be exercised directly.
