Bland annat har logiken kring att kontollera processorns mikrokod förbättrats.
Poängen med "chksys" är att den kontrollerar hur systemet är uppdaterat och hur mycket av uppgraderingarna som faktiskt är i aktuell drift. Vissa uppgraderingar påverkar i stort sett inte systemet, eftersom de bara tas i drift när de används. Andra som typ kärnan och mikrokoden, plus en massa annat är i drift hela tiden och kräver en omstart (reboot) för att kunna komma in.
Själv kör jag "chksys" i stort sett efter varje uppgradering och iallafall minst ett par gånger i månaden...
(om escape-sekvenserna funkar dåligt (som det ser ut som), så säg till så kan jag maila den istället...)
