----------
The regression risk of this fixed dbginfo.sh script and the updated s390-tools package is very low for the following reasons:
- the script is broken today on xenial, hence it cannot really get that worse...
- the fix was provided by IBM via a newer s390-tools package and was pretested by IBM before it was made available
- all this is limited to the s390x architecture and also to xenial (newer Ubuntu releases use newer packages)
- newer s390-tools packages that already incl. the fix are used in newer Ubuntu server releases and are known to work there |
