Hi ! within a jail there are at this time two possibilities of operation for the syscall getfsstat (which is used e.g. for the commands 'df' and 'mount'): security.jail.getfsstatroot_only = 0: getfsstat return all filesystems mounted anywhere at the machine security.jail.getfsstatroot_only = 1: getfsstat returns the filesystem where the jail-root is in and nothing more (mountpoints within the jails fs-tree are not returned) IMHO is this 2nd one not what is really needed: If we have additional filesystems mounted within the jails tree they should be visible too so that they are shown with a simple 'df' or 'mount'. I made a small patch for this which is available at <http://www.addict.de/unger/fbsd/patch-20050516/>; and should work against CURRENT and RELENG_5_4 Any comments ? I am not sure if there is locking needed (mtx_lock, mtx_unlock) around this new piece of code, at this time ot works for me without locking... Any other opinions ? bye, Juergen
