udisks2 and ACLs

[Allin Cottrell]

I notice that udisks-1.99.0 depends unconditionally on ACLs
(for handling permissions under /run/media). Since ACLs are
kinda redundant on personal laptop and desktop systems it
would be nice if this dependency were optional.

I'm attaching a patch to udisks' udiskslinuxfilesystem.c which
calls chown() if ACLs are not available. Since I'm not an
automake guy I'm not sure how to revise the configure script,
but the idea is that you should be able to do

--disable-acl

with the effect that ENABLE_ACL is not defined (otherwise it
is defined). And config.h.in should have added:

/* Enable ACLs */
#undef ENABLE_ACL
