How to guarantee Server boot up 100% ALWAYS

[manuel19]

I have installed to one of my customer a Firewall based on Linux fedora core 8.

The firewall server is running fine. At this day, the server have been working for 9 Days.

In the file: /etc/rc.d/rc.sysinit I add this lines:

/sbin/fsck -y
/sbin/fsck -y
/sbin/fsck -y
/sbin/fsck -u
/sbin/fsck -y

(5 times)

Using this config i believe i will always get Boot up in a 99.99%. (NEVER BOOT FAILS)

The hard disk is a Solid State disk. But this is NOT the point.

The point is that I don't want the firewall NEVER, NEVER fail on boot. But i know -->(ONLY Will FAIL if physical damage of the Solid state disk).

So, what you think? My 5 lines will do that?
What you think?

Note:* Do not recommend me have RAID's or other disk.
(I'm trying to avoid that)

The boot process will run fsck on boot when needed.
Further, if it is going to fail to boot, it will fail long before it reaches the point of running fsck from rc.sysinit, which I would like to point out, is within your root partition. In other words, it must already have mounted before it will even know of that file's existence, which means that the filesystem is already known to be fine.

As far as go boot failures due to corrupted filesystems, I really haven't seen much of that since last I used ext2. Ext3+ uses journaling, which pretty much doesn't have those automatic self destruct moments.
