I have on beutifull solution - DO Not login as a root
unless you have to! And if you are root, than be REAL
carefull.
Now, there is also another solution: Get HJ Lu base
distribution system disks. (with root disk). And make an
bootable image on a floppy. Now, whenever a screw-up
occurs, you just boot with them and copy all you want.
This Base Distribution, Mr Lu provides, is of
indespesable value. Not only it saves your butt, but it
lets you upgrade your binaries really quick. (Like mines.
I started in .95 days w/o jump tables, and just when
shared libs were a novelty. So most of my binaries were
either static or ldd on real old libs w/o jump tables.
How to upgrade them without installing whole thing? Well
you know the answer now, BAse Distribution.)
I would like to take this moment to thank H.J. Lu for his
immense work. Also thanks to all other Linux
contributors.
