# lib/log.sh - unified logging and error handling.

|

# Replaces the scattered `echo ...; exit 1` and ad-hoc `tee -a install.log`
|
|
# patterns with a single, consistent interface. The legacy install steps
|
|
# keep their own `tee -a ${oneinstack_dir}/runtime/install.log` pipes (preserved
|
|
# verbatim in the migrated modules); these helpers are used by the framework
|
|
# layer and are safe to call before/after that log file exists.

|
|
# oneinstack_dir is known).
