The chroot service module for PAM chroots users into either a
predetermined directory or one derived from their home directory.
If a user's home directory as specified in the
passwd
structure returned by
getpwnam(3)
contains the string
"
/./",
the portion of the directory name to the left of that string is used
as the chroot directory, and the portion to the right will be the
current working directory inside the chroot tree.
Otherwise, the directories specified by the
dir
and
cwd
options (see below) are used.

user's home directory, and the
dir

the user's home directory.
