Correct me if I am wrong, but I though that run level 1 still ran
/etc/rc.d/rc.sysinit and one of the things rc.sysinit does is mount
all file systems. The section that does this is:

# Mount all other filesystems (except for NFS and /proc, which is
already
# mounted). Contrary to standard usage,
# filesystems are NOT unmounted in single user mode.
action $"Mounting local filesystems: " mount -a -t
nonfs,nfs4,smbfs,ncpfs,cifs,gfs -O no_netdev

Also note that the when the list of file system types after the -t
option start with no, that it is a list of types to not mount. So
between this list of file system types not to be mounted, and the -O
no_netdev option, no file system that require network access should
get mounted here.
