I feel that things are actually progressing above my level of perception
here, however, I would like to mention that since my Redhat 4.x days i have
feared vendor kernels, and I never use them, for better or worse.

Also, maybe I screwed my own system - I don't think so, but maybe. I
prefer to stick with Linus's kernels, and sometimes, depending on the
changlog -ac kernels. As far as the kernel & init scirpts are concerned, I
axed any fsck'ing entries for reiserfs. [I assume that they were
unnessecary.] I used kgcc [w/Rh7.1] to compile kernels, until recently. And
I stayed current with the lkml, and the namesys page watching for obvious
updates that I needed.

The slowness [seemed] actually [to be] the process of starting & stopping
daemons. Almost like there was some sort of stigma about reading shell
scripts. All the binaries executed with appropriate haste.

As far as shoveling code. Sometimes the options used to compile packages
leaves me with a large bit of wonder. Strange and seemingly heinous changes
to the various utilities, etc. But, I have never had a cause to fault them
based on this. [Except that I have never found the magic that causes all the
SRPMS to be [re]buildable.]

So to sort it, I don't feel that being a moron caused to boot slow - unless
there is some wierd filehandling problem in bash2, or something that causes
severe slow-down when sourcing shell scripts. ???? However, Hans, I do
beleive you about Suse, and if I wasn't a cheap bastard I would probably buy
a copy.

thanks for all the response, and I am sorry if this does not belong here.
