Vague memory from 10+ years ago:
* Getting real deep with detecting OS/instruction set and edge cases
* Constantly validating permissions on every directory and file
* Constantly verifying checksums on everything put in place
* Concurrency controls to make sure the user didn't launch the installer twice, or the system wasn't live running when being reinstalled.
* Dependency verification was it's own rats nest of problems
* Uninstalling
Easier problems:
* Logging
* Status tracking (except for really large files things get weird...)
* Aborting/Cancelling install
- RajT88 3y agoLogging is easier - but deceptively so! Most problems have hidden depth, and logging is certainly a great example. So - do you want to log variables for debugging purposes once installers get to a certain level of complexity? Great. Now you're logging people's usernames and passwords, and you have to add some functionality to not do that.
