Having read the thread to date, I reckon you should: a) find(1) all schg files in your jails (was chpass the only one?) b) clear the schg flag on any such found as above (-R if you like) c) use mv as you originally intended (if they're still there :) d) chflags schg on all files that were originally set that way. If you do use cp instead of mv, make sure to use cp -p to preserve each file's owner/group/permissions/datestamp. e) make sure any and all symlinks still point to the right file/s. Personally I'd use cp -pR rather than mv in case I stuffed it up :) but then being perhaps overcautious I'd have started off with a 'ls -lR /usr/jail > listfile' (if I hadn't made a backup tar) to at least have a full list of what was where, with what user/perms etc .. Also read cp(1) re -R flag carefully .. if there are any hard linked files, as there may well be, then using tar to move these would be the safest bet anyway - plus you'd have a backup .. next time anyway :) Since it just failed to mv some files, you shouldn't need to rebuild if you can mv those files and reset their flags/permissions correctly. cheers, Ian
