Or you didn't notice. A single wrong bit in a movie is meaningless (typically). For me it was when I noticed just how many of my video files have changed their checksums over the years... while still working perfectly... of course, on occasion you run into damage that matters. Like ISO images that now don't work, videos that do get damaged, pictures that will not open, text files that don't work, etc...
Possibly, I don't normally run checksum verifications across everything. But I can't say I'm very worried since I've never had an ISO, tar ball, etc ever just randomly fail.
OpenSolaris has excellent package management.
Your familiarity is not relevant to someone who has never used linux OR solaris before.
Excellent? Anything would be better than what was there the last time I looked.
And yes, my familiarity is relevant when I'm giving my opinion. And on top of that someone just starting with OpenSolaris is going to have a much more difficult time getting help compared to someone starting off with a Linux distro like Ubuntu.
Or you just haven't noticed... there is also the issue of drives today having the same error rates as 10 years ago (reliability increased, but so did total size and miniturization, which counteracts reliability increases) while size vastly increased... 1/1TB on a 50GB drive is not nearly as significant than 1/1TB on a 2TB drive.
Since you mentioned it, I tested a few random bzip2 files I have here and all of them tested fine. I'm not saying that it doesn't happen, but I have yet to run into it.
I mentioned specifically that ZFS cannot do everything... but if the choice is between "data safety" and "online expansion/shrinking" (which note that I pointed out shrinking is a big lack in ZFS) then data safety should be your first choice.
Except that my data is safe where it is now. Sure, I could do more with regular off-site backups, ZFS, etc but frankly the hassle isn't worth it to me. IMO being able to use Debian instead of Solaris is worth the risk and at the end of the day that's all it is, risk management.
I wouldn't tell someone "smoking is perfectly fine! I have been smoking for years and never got cancer, so you should smoke too!"
But if you know the risks, it's still your choice and I know plenty of people that choose to smoke because they enjoy it despite the risks. And with all of the health nuts dying <70 from heart attacks and such I can't blame them. Life is too short not to enjoy it.
