Hi Vladimir,
pam_mktemp can work on filesystem which does not support ext2's file attributes.
For example, it works well on tmpfs.
For pam_mktemp to recognize the case and work without attributes,
the filesystem should return 'ENOTTY' (Inappropriate ioctl for device)
as a result of an setting/getting attributes call, as it tmpfs does.
But reiser4 returns 'ENOSYS' (Function not implemented).
Will you accept patch changing this code to 'ENOTTY'?
