As to the sorry 2G filesize limit in Linux, FreeBSD has had no such limitation since at least 2.0.0. The largest file I've ever created in FreeBSD was about 12G and had no problems seeking within. Another commented that he has created 4G tar files in FreeBSD. A tar file is exactly the same as any other file on the filesystem. Only difference is what you write in it. You can create a 4G tar file in FreeBSD but not in Linux. Altho in Linux you could use tar to write 4G to a tape (if the tape is big enough). *Thats* different. In prior employment I routinely used FreeBSD to copy a image of a tape to a file. Then turned around and shot that image back out to a blank tape. Often writing to 4 tape drives at once. With all that said, last time I checked there were numerous different patches available for Linux to "solve" the 2G filesize limit. One problem was they all required wiping your existing filesystems and starting over as the mod results in a non-standard non-compatible ext2fs. Other problems to consider are, 1) did the patch "get everything"? and 2) if everybody running Linux isn't using it, then its not that well tested. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
