Odd situation - SETUID fail

Hi,   This is a very specific and odd situation, I already discover the workaround  (odd too), but I like to try understand the real origin of the problem, if anybody have a explanation, I appreciate..   In small talk , the problem are with SETUID effect ( or not effect in this case).   For me , appear be a Bug on OpenSuse (kernel or glibc).   I install OpenSuse 11.1 on my new notebook and update the  packages and patches,  | cmartins@note-cim:~> uname -a  | Linux note-cim 2.6.27.7-9-pae #1 SMP 2008-12-04 18:10:04 +0100 i686 i686 i386 GNU/Linux  | cmartins@note-cim:~> rpm -q glibc  | glibc-2.9-2.11.1   After that I install IDS 11.5 UC3 Developer Edition and try to initialize it with very basic configuration.   When I execute the "oninit -iv" with user "informix" I got this (pay attention to ">" ):  | informix@note-cim:~> oninit -ivy  | Checking group membership to determine server run mode...succeeded  | Reading configuration file '/opt/IBM/ids1150uc3de/etc/onconfig.idsmoon'...succeeded >| Creating /INFORMIXTMP/.infxdirs...FAILED  | Creating infos file "/opt/IBM/ids1150uc3de/etc/.infos.idsmoon"...succeeded  | Linking conf file "/opt/IBM/ids1150uc3de/etc/.conf.idsmoon"...succeeded  | Checking config parameters...succeeded  | Writing to infos file...succeeded  | Allocating and attaching to shared memory...succeeded  | Creating resident pool 10570 kbytes...succeeded  | Allocating 100016 kbytes for buffer pool of 2K page size...succeeded  | Initializing rhead structure...succeeded  | Initialization of Encryption...succeeded  | tail: cannot open `$INFORMIXDIR/log/online.log' for reading: No such file or directory  | touch: cannot touch `/INFORMIXTMP/.idsmoon.alarm': No such file or directory >| awk: cmd. line:1: fatal: cannot open file `/INFORMIXTMP/.idsmoon.alarm' for reading (No such file or directory) >| mv: cannot move `/tmp/.idsmoon.alarm_9782' to `/INFORMIXTMP/.idsmoon.alarm': No such file or directory >| SENDER IS NULL NO MAIL WILL BE SENT >| /opt/IBM/ids1150uc3de/etc/alarmprogram.sh[517]: /INFORMIXTMP/.idsmoon.alarm: cannot create [No such file or directory]  | WARNING: server initialization failed, or possibly timed out (if -w was used).  | Check the message log, online.log, for errors.
