RFSTool on Linux
On linux, you can use the partition devices. For example, to use
/dev/hda2, you would write
server:~ # rfstool -p/dev/hda2 ...
This makes it much easier than the drive.partition notation (but it is also supported for linux).
Note: There is a bug in 0.7 that doesn't let you use this notation with the REISERFS_PARTITION environment variable, you must use the command line -p switch. Will be fixed in 0.8
