Hi,

I was thinking about symbolic links and space on the rootfs, would it be possible to move the entire /usr/ folder in to the 32gb mass memory and then use a symbolic link back to /usr/ ? If so,

What would be the up and downsides of this?

If it can't, how come?

file permissions are blown away after that.

or are you referring to /home/ ?
or /home/user/MyDocs/ ?

The reason they don't do this by default is, apparently, speed. See this thread.

Wherever is best really, but using symbolic links wouldn't it be possible to create a lot more free space?

If speed has something to do with it... what kind of differences would we be looking at?

There's a couple of issues - firstly (and most importantly) a lot of files in /usr are accessed before the other filesystems are mounted, so you won't be able to boot after moving the files. Secondly, as said, there's performance impacts - that's unlikely to be significant for just reading files, but some operations were benchmarked at something like 30x slower.

Ah, I didn't know about which folders are accessed before others, that's quite a big downside lol.

I guess though a lot of folders/files could be symlinked making a lot more room without too much impact, guess its just finding out which ones.
