Looks like the dhcp dependency is explicit: dhcp->bind->python3
recipes-connectivity/dhcp/dhcp.inc
DEPENDS = "openssl bind"
recipes-connectivity/bind/bind_9.10.5-P3.bb
RDEPENDS_${PN} = "python3-core"
In the build area: dhcp/4.3.6-r0/packages-split/dhcp-client.shlibdeps
dhcp-libs (>= 4.3.6)
bind (>= 9.10.5-P3)
glibc (>= 2.26)
Does it mean that python3 cannot be removed from target rootfs?
On the other hand, I see this file in rootfs: /usr/sbin/dnssec-checkds, which
requires python3 (#! /usr/bin/python3).
I believe this file gets installed from bind_9.10.5-P3.bb
do_install_append() {
sed -i -e '1s,#!.*python3,#! /usr/bin/python3,'
${D}${sbindir}/dnssec-coverage ${D}${sbindir}/dnssec-checkds
}
How can I move this file to a different package?
Thanks,
Carlos

when there are scripts in packages which requires a certain kind of interpreter
e.g. perl. python. bash, sh etc. system can autodetect that if interpreter is
specified in first line of script and add the appropriate runtime dependency,
since this script otherwise will be useless on target.
I suspect build for dhcp is adding such a file into dhcp-client package which
might be resulting in this implicit dep.
So please check it in the build area for dhcp especially under
packages-split/dhcp-client
for any such scripts.
if there are any and you find that these scripts are not required for normal
functioning of dhcp-client on target then move this script out into another
package where it might be more appropriate, that can eliminate this rdep
