`System.Directory.getPermissions` fails on read-only filesystem
Alain O'Dea reports in an email that:
Prelude> System.Directory.getPermissions "/usr/bin/ld"
*** Exception: /usr/bin/ld: fileAccess: permission denied (Read-only file system)That seems wrong.
An
access(*, W_OK)syscall by design should returnEROFSon a read-only file system by specification.This breaks Cabal on SmartOS since
/usris read-only by design and Cabal callsgetPermissions "/usr/bin/ld".
