Patch Rollback
All files that have been overwritten by a patch will be backed up in the directory
/var/adm/sw/patch/PHxx_yyyyy/ for UX 10.X
/var/adm/sw/save/PHxx_yyyyy/ for UX 11.X
When you remove a patch (swremove) these files will be restored to their original locations.
They are called patch rollbacks.
To avoid the original files from beeing backed up (which is a little bit risky) you have to do the
following:
for 10.X
create a dummy file PATCH_NOSAVE before swinstall:
# touch /var/adm/sw/PATCH_NOSAVE
for 11.X
use a special swinstall option:
# swinstall -x patch_save_files=false
