Those packages are great, my only complaint is that they (at least the Debian ones) don't include a changelog file. It would be great to see what's new through the standard Debian facility when they release new versions.
According to, IIRC, either Randy Russell or Alan Cox a decade ago, /opt was added to the FHS at the request of the proprietary Unix vendors. The idea of 'optional' 'third party' software is ridiculous in an Open Source OS. Throwing binaries, libraries, config etc. outside standard folders means long library paths, long binary paths, config that can't be backed up from a central location, etc.
Eg, say Debian include Chrome (as Chrome, not Chromium) in their next release. It will move from where it is now to the normal locations for unimportant software beneath /usr.
That said, I don't really care that much anymore. There's very little expectation for quality finished software on Linux in general:
* Most apps aren't packaged, even for the two major distros people use
* half of GUI apps still don't install with shortcuts
* WMs still invent their own .desktop replacements
* package descriptions for 'foobar' are 'the foobar package' or 'libtoolkit GUI for libfoobar'
* service descriptions are 'starts the foobar service'
* man pages either don't exist, point elsewhere or consist of 'debian says we have to have a man page, this is a man page, alas it has no content'.
Congratulations on great work! Alas Chrome had been unusable for me on Linux for the last couple of months... but this post just spurred me to find out why. Turned out my bookmark file was large - 6,000 items - with one particular bookmark (ironically an official Google blog entry on making your website faster) having gone forth and multiplied over 5,000 times. (perhaps aided by a bug in an unstable version?) The unfortunate and frustrating effect being that, on installing Chrome on a new computer - something I've done several times recently - everything would work fine until the sync kicked in. At which point opening or closing tabs would go 100% CPU for over a minute. It's only now in trying to save my bookmark file to try out this new version that I discovered the problem. Happy to be back!
