My intention was this ... but i just wanted to be sure that this will
have no conflicts, specially when a file descriptor obtained in one
non supported syscall is used in one supproted syscall or viceversa

as far as i know fopen is not a syscall is a libc function that
is suposed to internally use open, so it should also work with
booster too

not me i think, but if you mean by access the local volume directly to
diretly access the disk totally bypassing glusterfs we actually do that
when we need read only access from within the server itself as in our
application most data is read only and other data is never read before
it's totally written and is never modified once created, for writing we
always use the gluster volume for replication to work.
