You may be able to do:
in-target sed -i "$(echo '/<!-- Volume definitions -->/ {\nn\na <volume
fstype="cifs" mountpoint="~/earth" path="students/%(USER)" pgrp="users"
server="earth.lan" />\n}')" etc/security/pam_mount.conf.xml
also, I don't see why you need to run this in the target chroot, so you
can probably avoid some quoting problems with something like:
sed -i "$(echo '/<!-- Volume definitions -->/ {\nn\na <volume fstype="cifs"
mountpoint="~/earth" path="students/%(USER)" pgrp="users" server="earth.lan"
/>\n}')" /target/etc/security/pam_mount.conf.xml
or, even, just as you'd normally do it, with the embedded newlines
(which you were presumably avoiding because of the in-target, which you
don't need as it turns out)
Cheers, Phil.
