While installing MU7, patch numbers 109613-03, 109887-08, 109887-08, 110068-02, 109614-03, 109749-03, and 110069-02 might display the following benign error message in the patch log file :
var/sadm/pkg/pkgabbrev/save/patchid/undo: -- file unchanged compress(1) returned error code 2
Workaround: Ignore the message. The message indicates that compress(1) could not create an archive that is smaller than the original file. patchrm uses compress(1) to shrink the backout package.
