I quite agree with this post, especially the part about 'automatic
updates should just work' !!!! I am on the SuSE AMD64 list as well, and
about 1/2 of the posts there start out with 'My machine updated itself
last night w/ YOU (their auto-update package) & now it won't boot'. I
came to Linux from SGI's, *EXPENSIVE*, but darn close to 'it just
works'. I realize that for the cost savings of Linux compared to SGI, I
might have to sacrifice a bit of 'it just works', but the problem of
apparently-incompletely-tested OS updates seems far too prevalent in the
Linux world. I am here to stay (Linux vs. SGI), make no mistake, but
this is a situation that *SOMEONE* needs to drum up a fix for. I lay the
problem mostly at the feet of the distro-providers, since they DO make
$$$$ selling the software & would seem to be in the best position to
police their own distro. I have also had a few of RH's bug-blow-offs in
the more distant past (several years ago, circa 1999) & it does nothing
for the Linux movement or themselves professionally. SGI uses a fairly
sophisticated & probably proprietary suite of utilities to test new OS
components and assure that at least bugs aren't re-introduced and that
bugs that are claimed to be fixed actually are. I don't know who would
assume this responsibility in a distributed developement environment
such as Linux flourishes under, but it seems increasingly obvious that
*SOMEBODY* needs to. My $0.02 ....
There, I feel better now :-).
