Attached is my zipped syslog. From bootup, I touched a file, and then echo'd
some chars into it.  Everthing looks fine, even the file.

[root at JBMgateway-60b root]# touch me
[root at JBMgateway-60b root]# echo "thisisatest" > me
[root at JBMgateway-60b root]# cat me
thisisatest
[root at JBMgateway-60b root]#


If I reboot, then the system is hosed, and needs to be reflashed :
