Shrinking a UFS partition

G

Gambler

I have 70G /usr partition and 500M /tmp partition. I would like to reduce /usr to 60Gig and make /tmp 4Gig in size. Is it doable? I've searched this forum and the Internet, but haven't found any definite answers, let alone methods.

The reason I need a large /tmp is to store backups of /usr, /var and /boot before restore. It's also a good place to store backups in general, since it can be easily accessed in case of software failure.

Keep in mind that /tmp will be cleared during boot.
 
To clarify: I'm not really storing backups in /tmp, they are simply left there from the previous restore.

clear_tmp_enable looks like an interesting option. It kind of makes sense to clear a "temporary" directory on each booy. On the other hand, my /tmp usually has over 99% free space. Even when it's the default 500Mb partition. Lately, I started to make it much larger, precisely for the cases when I need to restore the system from dump's output.
