I can't speak for others, but I have a LOT of "funky sym-links like foo -> ../../bar/foo" and for good reasons. 1. NEXTSTEP uses ".dir.tiff" and ".opendir.tiff" as icons for directories (folders in the GUI) to override the default "folder" and "open folder" graphics. I generally set the same icon for the main and subdirectories in a project. I can do this with just the overhead of the symlinks and still am able to move the entire project easily from point to point in the filesystem. The links "just move" when they are relative rather than fixed. Also when I drag a project into NeXT-mail, the icons (and symlinks) travel with it. 2. I "mount" large portions of my OS through a rather complex hierarchy of symlinks (which can freely traverse hardware breaks, unlike hard-links). Some files are on multiple removable volumes. RELATIVE sym-links rather than fixed path symlinks allow me to preserve some portions of the filesystem so long as ONE volume is mounted which carries the file. I can still mount according to the actual volume mounted, "overwriting" cross-volume symlinks. When one of the appropriate magneto-optical disks is inserted and (daemon automounted by volume name), links are suddenly resolved at the link point, which resolves links as accessed throughout the filesystem. I have no direct net connection on this ultra-symlinked machine at present, so please forego flames and pointers regarding just how dangerous symlinks can be. I do know, but for now -- it works. --- UUCP bruce () TotSysSoft com SMTP lcbginge () antelope wcc edu NeXT-mail and MIME-mail welcome On Tue, 17 May 1994, Howard the Energizer wrote:

Sounds like a lot of people asked for it, but never used it.... If you did act on the results, (i.e. change the permission of some directories, etc.) did it have any ramifications? Did any code break? Should I post it to other mailing lists? Or is it too buggy?I certainly found it useful, and as far as I know few people have funky sym-links like foo -> ../../../bar/foo The only other problem I ran into, was that it wedged a sun386i when I ran it (probably becuase it ran out of swap space). It didn't break anything here. Howard Bampton Internet: bampton () cs utk edu Sys Admin, UT Knoxville, Tennessee Even the walls of Jericho fell.....
