Mount_lofs mount a svr4 loop back file system (lofs). This command is found in hpux 10.x (and later?) and solaris (I think) but not in irix.
Hacked up version of mount_lofs for irix 6.5.x. When mount_lofs.c is compiled to mount_lofs and placed in /sbin the command
mount -t lofs -o ro /from /to
will mount the "/from" over "/to" with "/to" being mounted read only.
Source mount_lofs.c
Don't confuse lofs with the linux mount option --bind.
