Overall notes:
1. Whenever mounting anything with mount_portal, always
specify absolute paths. By specifying an absolute path for the
configuration file, it can be re-parsed by sending a HUP to the
mount process. But since mount_portal calls daemon(), which
does a chdir("/"), the re-parse will fail unless the
specified file is absolute, not relative.
2. The mount point should always be specified as an absolute
path. Otherwise, umount may not be able to unmount it, as it
first converts a relative path to an absolute path before
checking against the mounted file systems (see
realpath(3)). If you mistakenly mount on portal, instead of
`pwd`/portal, you can umount with "umount -R portal", which
may seg fault, but it will umount.
