I thought I'd give lshw a try. Based on my brief experience, I'd recommend
others not do so.
This is interesting, and really sucks. I installed lshw via aptitude, read
the man page, then executed "lshw" with no arguments. It hard locked my
server, requiring a hard reset via the button, and upon reboot fsck found a
bunch of errors on / (ext2) relating to the files involved in installing
lshw, probably because they hadn't been flushed to disk yet when I ran lshw
and the machine locked up. After successfully rebooting, upon trying to
remove lshw I get the following:
[04:16:59][root@greer]~$ aptitude remove lshw

I cannot find a log file with the list of inodes/files that fsck deleted. I
watched the system boot, and there were at least 6 files or so that fsck
touched, all related to this package and/or aptitude/dkpg.
What all is affected by /var/lib/dpkg/available? How do I go about
repairing /var/lib/dpkg/available? How do I make sure I've cleaned
everything up properly that got screwed by this hard lock? I've searched
all the possibly relevant files in /var/log and can't find fsck logging of
the files that were affected by the fsck. My other filesystems are all XFS
and everything looks good there so I'm really only concerned with the
aptitude/dpkg stuff on the EXT2 / filesystem.
BTW, I'm really surprised a "stable" package I installed would hard lock a
machine in such a manner. That's very disappointing. Maybe I'm just a nub
for not thoroughly reading the man pages, but even so, no stable program
should cause a hard lock. If hard locking is a possibility, the package
shouldn't be in the repos.
Anyway, any help getting this mess cleaned up would be greatly appreciated.
I don't even know what all is broken at this point, but I'm pretty sure
it's only the stuff related to this package and related package management
files.
Thanks.
