While I understand where the "thank goodness" comes from, I do rather
wish that there were some standards for the on-disk format of UNIX
filesystems. Or am I the only person that has ever tried to transfer
UNIX filesystems on floppies between different systems? Or (soon)
transfer UNIX filesystems on floptical disks?
Most of the filesystems standards work seems to be technology specific
- such as, the soon-to-become-official standard for CD-ROM filesystems
and other optical disks. However, what I've seen of the CD-ROM
standard suggests that I am unlikely ever to be able to mount a CD-ROM
as the boot partition of my workstation...
Q: what is the UNIX community's particpation in various
technology-oriented filesystems standardization efforts? Does everyone
feel confident that present and future UNIX filesystem semantics will be
completely supported by these standards?
