This is from the Solaris 8 (pretty sure, they just got upgraded) man
page for chroot-
"The chroot utility causes command to be executed relative
to newroot. The meaning of any initial slashes (|) in the
path names is changed to newroot for command and any of
its child processes."
So / should be chroot-ed to /view/view0, and
ls /vobs
is the same as saying
ls /view/view0/vobs.
I can't see it any other way. I mean, if
chroot /view/view0
ls /vobs
gives you
/vob1
Then why bother doing a chroot at all? If this is the expected
behavior, why not just forget about doing a chroot- it is a no-op.
I don't understand- Please explain further,
this looks like chroot is NOT working right.
Confused,
