[cfgeeks] Solaris 10 Upgrade Error

[Liston Bias]

Seeing sporatic permission issues after upgrade from older Sol10 release 
to Sol10 11/06 release.

Anyone seen this?

bash-3.00$ /bin/hostname
bash: /bin/hostname: /usr/bin/sh: bad interpreter: Permission denied


Most stuff works fine, but critical apps are not starting because of this.

Likely to try just reinstalling the upgrade, but thought somone may know 
of another workaround.

Thanks,
Liston
