[R-sig-Fedora] Heads up - symlinked GotoBLAS in F14

[Roger Bivand]

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?

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
