I don't know about `cp' (I'm not sure how well it deals with device nodes, symlinks, etc), but yes, making an exact copy of the file structure should result in an identical jail. > Also can I hardlink a tree (outside) to inside the jail? Once you've made a hardlink, the system has no concept of the "original location". Both of the filesystem entries point to a structure on the disk; that structure doesn't refer back to those entries, point to one, and say "that's my parent!" However, depending on what you want to do, using NFS may be a nice approach. You can make a directory and its children read-only to the jail, but read-write outside of the jail. It's also a lot clearer later on that a particular directory is used by several different systems on the same machine. =2D-=20 Kirk Strauser In Googlis non est, ergo non est. --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQA+ibKa5sRg+Y0CpvERAvrEAKCa1/YRYq11p/qRHGFRrsWikueBsgCghwSC CtgY16B0wy/zRKymN2ExDDQ= =LJkY -----END PGP SIGNATURE----- --=-=-=--
