To all but a handful of a handful, a perfect filesystem would be boring: files would be where you expect them to be, corrupt files
would never be an issue, and a power outage would result in nothing more than a few moments of darkness rather than minutes or hours
of lost work. Even so -- perhaps a clue that the perfect example is far, far away -- the news on the Linux filesystem front is
pretty exciting of late. In a low-key technical session Friday morning at
ALS, kernel
hacker Daniel Philips announced to the world the
minor revolution he's planning -- which could end
up replacing Linux's old standby ext2fs (and it's coming replacement ext3fs) with his
Tux2
filesystem. Though Tux2 is an ext2 cousin in many ways, it carries at least one crucial improvement: according to Philips, you
can literally pull the plug on a system running Tux2 and expect not to lose files or spend minutes watching fsck crawl by.
