If I understand this correctly, you have: /usr/src/sys/amd64/conf -> /usr/src/sys/amd64/conf/ So /usr/src/sys/amd64> cd conf will result in an attempt to cd to /usr/src/sys/amd64/(conf=/usr/src/sys/amd64/)(conf=/usr/src/sys/amd64/)... This obviously looks wrong. :-) Probably you should try to remove the conf@ symlink (note: just a symbolic link, not a "real" directory!) by invoking /usr/src/sys/amd64> rm conf or /usr/src/sys/amd64> unlink conf With "man unlink" you'll see that the rm and unlink commands can easily remove a symbolik link. :-) If this _fails_, you can try the following, which is a little bit dangerous and you should know what you're doing: Use a live system or single user mode (/usr partition _not_ mounted), and call # fdsb <device> Then in this program, navigate to /usr/src/sys/amd64 (or to /src/sys/amd64 if /usr is on its own parition), for example by cd /src/sys/amd64 and then use the del conf command. When the change has been writte to the file system, perform a file system check # fsck <device> Then you should be able to mount it again. Note again: This is an extremely dirty method! See "man fsdb" for details. But I assume you won't have to do this. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
