I agree with the proposal. I'm on the other side with respect to size of root ... 2 GB doesn't seem safe enough given the current 1.1 GB size we have. But on the other hand, repartitioning later is probably quite practical. -- James Cameron http://quozl.linux.org.au/ ___

[OT] XO-1 radio range testing team at Parkes Radiotelescope

2009-07-27 Thread James Cameron
A set of XO-1 units was demonstrated by Petria and James Cameron at Parkes Radiotelescope a week and a half ago, with about 6500 visitors to the site walking past the demonstration. It was a hit with the kids, who automatically clustered around the table to fit the available keyboard slots. The p

The filesystem is no longer internally compressed. The current size for the XO-1.5 system is 1.1 GB. 2 GB gives some headroom for growth and for temporary overages during updates. Walter Bender wrote: > Why such a large system partition? > > -walter > > On Mon, Jul 27, 2009 at 6:17 PM, Mitch B

Disk layout for XO-1.5

2009-07-27 Thread Mitch Bradley
This is a request for comments on a proposed disk layout for XO-1.5. XO-1.5 will have "managed NAND" instead of raw NAND, so we can use conventional filesystems instead of e.g. JFFS2. Proposal: The internal NAND storage will be partitioned with an FDISK partition map, into three partitions: /
