Another option is to configure a post-build action. This is available
in +Global settings+. It must point to a script relative to the root
of your openadk working copy. It will be invoked as part of the
-+*-imageinstall+ step with $ADK_TOPDIR as first argument. You can use
++-imageinstall+ step with $ADK_TOPDIR as first argument. You can use
it e.g. to modify the +root_*+ filesystem before bundling it.

+analyzing logs
+~~~~~~~~~~~~~~
+
+Since embedded systems usually avoid writing continously on non-volatile storage
+(to avoid waer-out of the storage device) there are no logfiles under /var/log and
+/var itself is mapped onto a RAM based filesystem.
+
+Instead the syslog daemon logs into a ciruclar memory
+buffer. The size of the memory buffer is by default 32KiB and can be changed in the
+busybox configuration.
+
+To access the content of the buffer the +logread+ utility is used to dump the buffer.
+To get a continous output of the logbuffer -f has to be added as option.
+
+---------------------
+Usage: logread [-fF]
+
+-f Output data as log grows
+-F Same as -f, but dump buffer first
