Heads up - symlinked GotoBLAS in F14

Hi, I installed F14 on release, but was diquieted to note that my symlinked GotoBLAS (http://cran.r-project.org/doc/manuals/R-admin.html#Shared-BLAS, foot of paragraph) prevented R (compiled from source, no special configure options) from loading - everything had been fine on F < 14. It seems that: cat /selinux/booleans/allow_execstack is 1 1 on my RHEL systems, but became (?) 0 0 in F14. Could anyone with F < 14 check its value there?
It is 1 1 on both my F13 and F12 boxes (Time to upgrade at least one of those I guess...) but I haven't used any BLAS other than the one supplied in the R sources. HTH G
The "fix" on F14 is: System -> Administration -> SELinux Management -> (root password, wait), then Boolean -> global | allow_execstack | Allow unconfirmed executables to make their stack executable [tick] The comments suggest that this is not a good policy! Following the adjustment, the booleans are 1 1, and R loads with symlinked GotoBLAS on F14. Roger
