Makes sense, and that's why I started with touch-files following an
established example so as to support anything regardless of matching,
only an admin (or wrap-package) who'd touch the file is needed. ;)

I think a "case" would be more readable and conservative on resources
than a stack of if-elif-else-fi (don't have to call an external program
too many times) and would suffice especially since you are comparing
fixed strings or, at most, simple wildcards here.
In the patch itself, here's a bit that worries me: either I've had a
night too sleepless, or there is a logical error here:
+ STR_KERN_MAJOR=`echo "$PKGFMRI" | sed
+ if test "$STR_KERN_MAJOR" = "5.12"; then
+ ###(comments snipped)
+ HOST_OS_MAJORVERSION=`echo "$BRANCH_VERSION" |
cut -f2 -d'-' | cut -f1,2 -d'.'`
+ if test "$HOST_OS_MAJORVERSION" = "5.12"; then
"$BRANCH_VERSION" | cut -f2 -d'-' | cut -f6 -d'.'`
+ return 0
+ errorprint "Failed to parse the Solaris
kernel major version."
+ exit 1
Here you have STR_KERN_MAJOR=="5.12" (fixed, no more, no less), then
assign BRANCH_VERSION to the same "5.12" and try to `cut` major/minor
versions out of it. You do get "5.12" again as major, but minor without
the dash-separated part of the FMRI is meaningless (and ends up empty).
Otherwise, cutting the "5.11", "0.5.11" or "5.12" parts seems to work
Also, in line 10 (added comment for OI Hipster string) there is "of"
instead of "or" ;)
