lofs

UNIX Solaris

hi all,

I was going through the /lib/svc/methods/fs-root file
and found this command

/usr/sbin/mount -O -F lofs $MOE /lib/libc.so.1

can anyone please explain to me what it does.
i know what lofs does what lib.so.1 and what mount is , but am not able to interpret it as its written in the script.
Also as i searched through google ,found out that MOE :measure of effectiveness ,can you tell me how is that in regard to this statement
I am a relatively new guy to this, so would be glad to have some assistance

Thanks

Well, $MOE is just a variable name in the script. It could be $LARRY or $CURLY and it would work just as well. But good programmers pick good names for variables and in this case MOE means "most optimal execution" or something like that. The idea is that you have a bunch of libc libraries, each optimized for different cpu's. Then you figure out what capabilities your cpu has and you mount your best libc onto the the official libc name. The mount goes away with each reboot, so if you power-down, upgrade your cpu, and reboot, the OS will come up using whatever new features you got with the upgrade.
