Help! I screwed my system up!

I don't know what happened. When my system boots it doesn't appear to be running any boot scripts. I can't remember exactly what it says but here's what I remember:

Code:

INIT 2.85 Booting

tty1
(none) login:

If I try to login it says something about the filesystem being readonly and that it can't change tty1. Then another login prompt appears.

Something similar happened to me quite a while back, and it was because I mistakenly, as root (naturally) changed all the files to read-only with a chmod command. As a result I couldn't run anything, even as root. Not even chmod again to fix it.

I reinstalled.

Afraid this is of no help, but at least you know you're not alone.

i have no problem with lfs except iproute2(which is solved now),
then i have made a backup image using partimage,( the time can't be ignored)

http://www.partimage.org

i am doing build blfs over lfs now, i made a mistake on linux-pam part,
so i couldn't loggin my new blfs, but because of my partimage backup, i am not fear my mistake.

i have built lfs using chrooted environment on debian sid.
now, i am compiling firefox-1.0.1.

Well, I managed to fix my problem. A few weeks ago I discovered UPX. I went around randomly compressing my executables. One of those being bash. Apparently at boot time a UPX packed image of bash will not run. I have no idea why. Since bash is used for running my boot scripts nothing was getting started. Anyway I replaced the compressed version of bash with an original and everything was back to normal.

Glad to hear it! I remember clearly the sinking feeling when I was informed by the operating system that there was no such thing as bash. At that point I knew I was a goner. I almost passed out... Not the most pleasant day with Linux, but it was all my fault!
