O.K. then would you please do the following:
o delete all your shared libs
o put your hand on the power switch
o start to copy new shared libs
o as soon as you hit the return key for the cp
o power-off
Now please tell me how to:
o boot into single-user mode from the hard disk
o if you can't do that then boot off whatever
rescue disks you use, and fix whatever is
wrong with your system.
o tell how long it took to get your system up and
running
I'll wager it'll take longer than having a system that has
a robust boot environment which will allow booting into single
user mode and simply copy whatever needs to be copied and run
ldconfig.
I'm not talking about what can and can't be done by
skilled and practiced system hackers. I'm worried about
time ('cause that's expensive) and the exposure relying
on a small pool of skilled people brings. I want
to minimize the risks. Disk is cheap, people are the
high value item in this business.
Cheers, Liam
