Hello all,
Is it possible to conditionally require a restart for an install?
Yes.
Here's my situation:
Version 2 of my app cannot be properly unloaded without a shutdown, but version 3 can.
So, for a fresh install, nothing exists, so just install the software without a restart. If you are installing 3.0.1 and 3.0.0 is installed, a restart still is not required. But, if you are installing 3.x (or even any version) and 2.x is installed, a restart is required.
Here is how this can be done:
- make a distribution with 2 packages: one for the the payload, one of the restart action
- in the payload package, do everything as usual. Do not require a restart upon a successful installation.
- in the restart package:
o require a restart upon a successful installation o do not install anything
- in the distribution:
o set a requirement for the choice corresponding to the restart package:
unselect the choice when a requirement is not met (for instance a file specific to your 2.0 version is installed or you can call a shell script to do more advanced stuff that you would not be able to do via JavaScript).
Is there an easy way to choose whether to use JavaScript or shell? I need to do approximately this: kextstat | perl -e 'while (<>) { exit 1 if /com.test.example \([1-2].*\)/; }' That is, if a kernel extension called com.test.example is loaded, and if it's version 1.x or 2.x, require a restart. Else, do not require a restart. Thanks, Andrew Keller _______________________________________________ Do not post admin requests to the list. They will be ignored.
