While normally the 'mmap' file reading is better utilizing resources,
it has also its odd side with handling errors - so while we normally
use the mmap only for reading regular files from root filesystem
(i.e. lvm.conf) we can't prevent error to happen during the read
of these file - and such error unfortunately ends with SIGBUS error.
Maintaing signal handler would be compilated - so switch to slightly
less effiecient but more error resistant read() functinality.
