ZFS update for the bleeding edge

Saw a post on zfs-discuss today, ZFS for Leopard source & binaries have been posted to zfs.macosforge.org. This includes some new fixes over the one on ADC, but it is also bleeding edge - there's no PKG file to install, so you have to be comfortable manually copying a bunch of files at the command line with sudo to use this, and there are a bunch of known bugs (listed at zfs.macosforge.org).

It's not an official Apple release, so if you break anything on your system with it, I'm sure their response is going to be "reinstall everything - you did have backups, right?"

That said, Noël's announcement said that he has his homedir on ZFS now, which is what I've been wanting to do ever since I heard there might be ZFS support in 10.5.

Here's the list of bugs fixed in the 102A rev:

Bugs Fixed in this Rev:

• 5448925: sync ZFS with Solaris build 72

• 5621659: assertion failed in /Users/local/zfs-101-latest_fixes/zfs_kext/zfs/zfs_dir.c line 730: error == 0


• 5643944: ZFS get/set and mountpoints are misbehaving


• 5645880: Finder copy and “delete” broken in zfs-101 plus fixes..

Remove APE before insalling 10.5

There are known issues with Unsanity's APE extension and 10.5. Remove it before upgrading to 10.5.

You may not realize you have APE - Logitech's mouse driver is known to use it, and AudioHijack Pro's Instant hijack is also known to use it.

If you are getting the blue screen and no loginwindow, you can nuke APE without a reinstall with the following steps:

1. Boot into single user mode by holding Apple+S on startup


2. fsck -fy /


3. /sbin/mount -uw /


4. rm -rf /Library/Preference Panes/Application Enhancer.prefpane /Library/Frameworks/Application Enhancer.framework /System/Library/SystemConfiguration/Application Enhancer.bundle /Library/Preferences/com.unsanity.ape.plist


5. sync;shutdown -r now

Edit
John Gruber has more background on this in an article he wrote on Daring Fireball here and Apple posted a KB article about this here.

The Pug Automatic posted a nice little applescript you can add to your Finder toolbar that lets you just click the button to open the selected files/folders in TextMate.
