ok,i have a question regarding a certain situation involving links in typical unix filesystems from that dude randall schwartz who wrote learning perl (i hope he doenst mind me quoting his "stuff"),ok ill cut it short to the quote

" There's another rule about the links in directory listings: the inode numbers in a given directory listing refer to inodes on that same mounted volume.[] This rule ensures that if the physical medium (the diskette, perhaps) is moved to another machine, all of the directories stick together with their files. That's why you can use rename to move a file from one directory to another, but only if both directories are on the same filesystem (mounted volume). If they were on different disks, the system would have to relocate the inode's data, which is too complex an operation for a simple system call."

my question is why is it too complex for a system call, and how is this actually achieved ? where can i read this up ? cheers monks! (spx2 raises the bottle to the air in honor of all monks on perlmonks :) ) thank you
