Hi,
I upgraded from GS 2.0.2 to GS 2.1-beta2 and most went smooth.
Environment: Ubuntu 9.10 32b, Sun JDK 1.6_22, JAI+ImageIO, Tomcat
6.0.29, no Gdal bindings.
Only had 2 issues when adding/using the ImageMosaic Store. Source data
are directories of GeoTiffs preworked with gdal_translate and gdaladdo
(not gdaltindex). The GeoTiffs are aligned historic topomaps (100s)
divided over periods of time using directories per period with softlinks
(ln -s) to the originals. Adding a IM Store was working in 2.0.2,
though there had issue (2) below. Issue (2) I could resolve, issue (1)
partly by making regular copies (cp) i.s.o. softlinks. So what remains
is my request to support softlinked files in the ImageMosaic plugin.
Details below.
1) errors adding the ImageMosaic store

First thought it was this issue/solution:
http://geo-solutions.blogspot.com/2010/05/fix-geotools-and-geoserver-not-able-to.html
and set JreMemoryLeakPreventionListener attribute appContextProtection
to "false" in Tomcat's server.xml configuration.
But the real issue appeared that the ImageMosaic plugin was not able to
use (soft)linked files. This was working in GS 2.0.2.
2) problem: Exceptions: "Too many open files" when reading layer
set JAI_IMAGE_READ to false for layer
