Gang,
I am purposefully posting to 'chat' to avoid getting very
involved, however, I have some good news (and some minor
bad news) about V5.0. Suggestions about reading release
notes, etc need not apply -- because the principle of
least astonishment (POLA) needs to apply no matter what.
Good news: it is incredibly responsive. I have been
impressed with it, and the improvements
appear real. I am NOT easily impressed.
Bad news: the filesystem stuff is a little unfriendly.
firstly, it seems to 'modify' already existant
FFS filesystems too much to maintain full
compatibility with older systems. This is true
even when passively doing a mount of older
filesystems, and only reading (but not RO.) Also,
I am using VINUM with debug mode off, and that
has some source code errors for that mode.
VINUM has also modified the on-disk structure
too much for reverse compatibility (maybe related
to other filesystem changes instead of VINUM.)
There is *definitely* improvement in responsiveness over
older versions of the system. There are also some problems
of the code being 'green.' I have participated in worse
releases, and 5.1 will probably be incredibly good.
A better designed kernel restructuring would have been better,
but otherwise, the results are very good.
John
