A gotcha with the automounter and loopback mounts
On Solaris, there is a combination gotcha with the automounter and mountson the same host. It goes like this:
- your fileserver normally has /dev/whatever mounted on /export/foo.
- your generic automounter configuration mounts fileserver:/export/fooas /foo.
- you need to do some maintenance to the filesystem, so you unshareand unmount /export/foo.
- after you're done you try to remount it, but you get a message thatthe mount point is busy. The only mention of
On storing source code in some non-text format
Every so often these days there is some agitation that program sourcecode should not be stored as text but instead in some more intelligentand more abstract form, and just presented as text by editors.
This is the programming language version of the web's 'semantic markuponly' movement, and it fails for the exact same reason that only a smallfringe writes in purely semantic markup: the appearance of the text is important, it is not an afterthought.

Why ZFS's data integrity is less important than Solaris's usability

Paying for security exploits
Somewhere out on the Internet, there is probably someone waxingindignant right now about how companies generally now have to payrelatively substantial bounties for security exploits in their products.After all, why do the security researchers now demand payment for theirresearch work?
I thin that there are two reasons: the obvious reason and the deeperreason.
The obvious reason is that companies are competing for new securityexploits with the criminal groups exploiting security vulnerabilitiesto do various bad things. Said groups pay well for new vulnerabilities,because there is
