Or create a new toor user? Look in your /etc/passwd file, the toor user already exists, its normal use is for /bin/sh login to root, but it can still be used for your issue here. > > I think the same will be with .profile which also looks like it's > hardlinked. Yes, but the pkg system is ONLY going to mess with /root, if you use /toor for your purpose it wont mess with pkg. However, you well have to update things from /root to /toor manually, but that rate of change is very very small. > > Wouldn't pkg already have to handle this for normal port packages > somehow?

The norm is there are very few cross directory links and this is very rarely an issue unless someone modifies the system in a way outside of the norm. Having /root as a seperate dataset is outside the norm. Note this also places /root outside of the boot environment directory which may bring other issues in the future. Ports should all install stuff inder the /usr/local hierarchy and that is usually self contained, so hard links are not an issue there. Further note, if you have made /usr/local its own dataset your defanitly going to have issues with boot environments if you try to run more than 1 version of FreeBSD as /usr/local is pretty version dependent. /var is a whole nother crap mess with boot environments, pkg and multiple versions cause pkg stores its caches and databases in /var and /var is not part of the BE. > --GrzegorzJ -- Rod Grimes rgrimes@freebsd.org
