You're reading it wrong. :-) If you try the command % ls -li /rescue then you'll see that all the files have the same inode number, i. e., they are _the same file_ (hardlinks), so only _one time_ the disk space is allocated - for _one_ file (one binary with many different names). > There > are also those pkg.sql backups, @ about 10 MiB apiece.

No, that's entirely possible. Just create different partitions for all the "other" things that can be left off of / and still keep things operational. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
