To quote the New Hackers' Dictionary: :SMOP: /S-M-O-P/ /n./ [Simple (or Small) Matter of Programming] 1. A piece of code, not yet written, whose anticipated length is significantly greater than its complexity. Used to refer to a program that could obviously be written, but is not worth the trouble. Also used ironically to imply that a difficult problem can be easily solved because a program can be written to do it; the irony is that it is very clear that writing such a program will be a great deal of work. "It's easy to enhance a FORTRAN compiler to compile COBOL as well; it's just an SMOP." 2. Often used ironically by the intended victim when a suggestion for a program is made which seems easy to the suggester, but is obviously (to the victim) a lot of work. >>> Here's my disklabel (same for both drives): >>> # size offset fstype [fsize bsize bps/cpg] >>> a: 144585 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 8) >>> b: 803250 144585 swap # (Cyl. 9 - 58) >>> c: 17928698 0 unused 0 0 # (Cyl. 0 - 1116*) >>> e: 16980863 947835 4.2BSD 1024 8192 16 # (Cyl. 59 - 1116*) >>> >>> My plan is to sync the the 'a' partitions, so if one disk dies, the >>> other root partition is useable.

With Vinum, I'd expect: # size offset fstype [fsize bsize bps/cpg] a: 17928698 0 vinum 0 0 # (Cyl. 0 - 1116*) c: 17928698 0 unused 0 0 # (Cyl. 0 - 1116*) Greg -- When replying to this message, please copy the original recipients.
