I suggest Reiser4 here, too. I'm using it with gzip compression turned on and my install went from 1.5gb to 500mb. I was quite impressed.
This is running on a Dual P3 even (MyRouter)
I'm also using it on a pair of K6 systems and it loves it. Nice to install a decent Gentoo install on a 2gb with a gig left (384mb Swap). Leave the bigger drives to store user data (one with 80gb, one with 250gb). |

So, basically for a good partition that will only hold portage and my overlays, I need to make the partition as follows and should be golden (with reiser4, of course)?
| Code: | | mkfs.reiser4 -o create=ccreg40,compress=lzo1 /dev/xxx |
Is this good / right? Does anything special need to go in the fstab? |

Looks good. If you have a decent cpu, I might even use gzip for something like the portage tree since it's highly compressible.
You mount it just like any other partition, so in your fstab just put your usual options like noatime and list the filesystem as "reiser4".

Yeah, I actually ended up using gzip compression, and I mounted with options noatime,nodiratime. Actually, what I used was
| Code: | | mkfs.reiser4 -o create=ccreg40,compress=gzip1,compressMode=force,cluster=8K,fibration=lexic_fibre,formatting=tails /dev/sdc2 |
as per some suggestions in a reiser4 thread. I definitely notice the difference in syncing portage and the overlays, much faster. Maybe I should redo it with lzo though, as I'm not as concerned about how much space it takes up as I am performance. Thoughts or anecdotes? |

Remove that, you don't want to force compression. Reiser4 will dynamically determin whether a file can be compressed. Performing that whole compression procedure on already compressed files or on uncompressable files is a big waste of time. |
