The OS X Installer replaces the OS X standard /tmp symbolic link with a real directory.

Normally, /tmp is a symbolic link to /private/tmp. After running the OS X 4.2.0-914-rc1.1 installer, I ran into problems with other applications crashing (particularly Adobe apps). After some searching I discovered the /tmp directory had been replaced and the permissions reset.

The installer should not be writing in / and, I believe, you need to include the IFPkgFlagFollowLinks = Yes flag in the package's Info.plist file.

I'm evaluating several wikis and this seems like a pretty big deal breaker for TWiki.

its a bit strange, I'm not writing to /, I'm putting files into /tmp . guess I still have alot to learn about how OSX is not unix.

Did TWiki install and work? (Yours is the first detailed feedback that I've received in about 2000 downloads)

(I'll release an update soonish)

ok, I've fixed this, and some toher issues that crept in (I use the same code and files to generate all the installers except windows)


-- SvenDowideit - 11 Dec 2007

closing as fixed.
