I hope there is a simple answer to this question (fingers crossed): how
do I overwrite an existing partition (hda2 for example) with all zeros
(essentially blanking the partition clean in preparation for installing
Lenny), without destroying the partition table?
Why do you think you need to blank the partition before installing
lenny? There *are* reasons to do that, but they have nothing to do with
the installation of a new OS.
(reiserfsck --rebuild-tree) has a nasty habit of necromancy. In
particular, it might link files from the old file system into lost+found.
It can also destroy the heck out of your file system if you happen to
store a reiserfs file system in a file. (e.g. [reiserfs] ->
/home/bss/Sid.qemu -> [reiserfs]).
1. Old installation using one of more reiserfs file systems.
2. Install Lenny without wiping; use one or more reiserfs file systems.
3. Worst-case scenario file system failure.
4. (reiserfsck --rebuild-tree) -> Links files from the old file system into
the new file system.
You're joking. You *must* be joking.
But then, I never did --rebuild-tree.
If you are going to put reiserfs on a block device, it is not overly cautious
to erase the block device, to avoid (reiserfsck --rebuild-tree) from
While I had lots of problems with ReiserFS 3, v3.5 was really darned
stable. Only reason I moved away from it was that it was
