For those of you that have upgraded to 1.1.3 using the official Dev Team upgrade version and have now discovered that their system disk partition is approximately 21 Mb smaller than it was. I experienced the same problem and since there doesn't seem to be an immediate fix other than to re-upgrade using the Nate True version, I started hunting for parts of the OS that I could delete to make additional space. Since I only speak English I figured that the best places to look were anything to do with multi-lingual support that I wasn't going to use.

Note - you should KEEP A COPY OF ANYTHING YOU DELETE during this process just in case you run into problems later!

1. First place to look is in the keyboard dictionaries in

/System/Library/KeyboardDictionaries/

I removed dictionaries for Spanish, French, German, Italian and Dutch (deleting all files NOT starting with 'en_'). To be on the safe side I left UK and US English, although I doubt I actually need both. This freed up approximately 5Mb of space.

2. Second place provided much more fruitful - typeface cache

/System/Library/Fonts/Cache

You will notice some of these are HUGE - there are 2 typefaces for Chinese and 2 for Japanese with a cumulative size of 42Mb (!!).

STHeiti.ttf
STXihei.ttf
HiraginoKakuGothicProNW6.otf
HiraginoKakuGothicProNW3.otf

Here you have 3 options:

a. Delete all 4 files - this means that VISITING WEBSITES THAT USE CHINESE OR JAPANESE CHARACTERS WILL CRASH SAFARI, BUT it will gain you lots of space.

b. Delete only the STHeiti and STXihei files - these are the Chinese fonts and are very large - approx 28Mb. Then ensure that in Settings->General->International you have the 'Asian Font' set to 'Japanese' (i.e. the files you haven't deleted)

or

c. Delete only the Hiragino files - Japanese, and set the Asian Font setting to Chinese.

In total this can free-up up to 47Mb of space on your system partition with the caveat that if you look at websites with asian typefaces you will need to keep either the Japanese or Chinese files in order for Safari not to bomb when showing these sites. I now have more free space than was available under 1.1.2.

and why is that better than moving /Applications to /var/root ?
What you are doing is simply damaging your system.

Absolutely true this does damage the system and ultimately I think a better fix would be to re-upgrade to 1.1.3. in a way that preserves / restores the size of the system partition.

I have read quite a few posts from users that have got into difficulty with moving the /Applications folder - e.g. getting into a state where Springboard continually attempts and fails to restart, or installed applications not showing up. I haven't tried this, but it doesn't seem risk-free either.

I don't believe this solution is any better - it's just an alternative solution to free up quite a lot of extra space. If you don't like the idea, don't do it!

Well, this approach I used always and this way of fixing it in 1.1.3 worked fine for me.

I simply used BossTool to moves Applications, Ringtones and Fonts to the other partition and I now have 103MB free out of 266MB. All seems to work fine.

This is essentially what BossTool did:

Moved Applications from / (default) to /private/var/applications

Moved /Library/Ringtones (default) to /private/var/Ringtones

Moved /System/Library/Fonts (default) to /private/var/Fonts

...and of course it created a symlink to the new folders.

I would love a way to resize the partitions.... I'd make the OS partition about 500MB instead of only 300MB... I wonder what Apple is planning on doing regarding this since their firmware seems to get more and more bloated!
