Mount options (exec...) not working for AIX NFS filesystems.

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: Mount options (exec...) not honored for AIX NFS mounted filesystems. RedHat 8.0 is the client; AIX 5.1 is the server. /etc/fstab: dosxx:/linux /images nfs sync,exec,suid,dev,tcp,rsize=8192,wsize=8192,... After mount performed, cat /proc/mounts reports: dosxx:/linux /images nfs rw,sync,nosuid,nodev,noexec,... Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Specify exec mount option for an NFS filesystem 2.Mount the filesystem 3.Check /proc/mounts or try to execute a Linux executable or shell from the mounted filesystem Actual Results: Cannot execute any files from the NFS mounted filesystem (/bin/sh: bad interpreter: Permission denied) Expected Results: Being able to execute Linux executables and shells from the mounted filesystems. Additional info:
From the error message, it seems as if the actual problem is elsewhere (_bad interpreter_). Please investigate with ls -l before concluding that the mount options are the problem. There is really no way that util-linux or even the kernel is changing its behaviour based on the fact that the server is an AIX one.
