Hello Jan,

rvmsizer is really a nice utility. Thanks Michael!

The "total directory size" is for some reason remarkably bigger than the
(total!) calculated RVM usage. As it is just what stat() says about the
directory sizes, it does not have much to do with the internal
representation, but still a bit strange.

As a "Coda usage report",
the numbers for some data (software) present on Coda here:
--------------------
$ rvmsizer sw
13213 directories, 108686 files, 15039 directory pages
total file size        3949049214 bytes (3766.11MB)
average file size      36334 bytes
total directory size   60239872 bytes (57.45MB)
average directory size 4559 bytes
estimated RVM usage based on object counts, 58294644 bytes (55.59MB)
estimated RVM usage based on 4% rule,       160371563 bytes (152.94MB)
--------------------

Looks like my 768Mb RVM server can serve about 50G software,
despite a lot of small wrappers and forests of symlinks. Good.

See you,
