https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272706 --- Comment #4 from Andrew "RhodiumToad" Gierth <andrew@tao11.riddles.org.uk> --- (In reply to Andrew "RhodiumToad" Gierth from comment #3) I think I figured this one out, it happens when nullmounts are involved, even if the jail's root directory is not itself the mountpoint of a nullmount. e.g. mkdir /some/dir mount -t nullfs /path/to/real/jail/tree /some/dir jail -c path=/some/dir/somejail at this point, executing procstat (or possibly other vn_fullpath clients) inside the jail returns paths based on /path/to/real/jail/tree/somejail (and not /some/dir/somejail). -- You are receiving this mail because: You are the assignee for the bug.
