shadow-4.1.5.1-r1 install failed [SOLVED]

[selig]

I am having problems updating shadow on a new install of Gentoo. I am still running it from the install CD and doing this in a chroot. It looks like it cannot set SUID permissions for some reason?

Code: Select all

libtool: install: /usr/bin/install -c vipw /var/tmp/portage/sys-apps/shadow-4.1.5.1-r1/image//usr/sbin/vipw
make[2]: Leaving directory `/var/tmp/portage/sys-apps/shadow-4.1.5.1-r1/work/shadow-4.1.5.1/src'
ln -sf newgrp	/var/tmp/portage/sys-apps/shadow-4.1.5.1-r1/image//usr/bin/sg
ln -sf vipw	/var/tmp/portage/sys-apps/shadow-4.1.5.1-r1/image//usr/sbin/vigr
for i in su; do \
	chmod -f 4711 /var/tmp/portage/sys-apps/shadow-4.1.5.1-r1/image//bin/$i; \
done
make[1]: *** [install-am] Error 1

Are you sure this is the first error ?

Yes, there were no errors in the build process - until this one during install phase.

Code: Select all

livecd ~ # touch test
livecd ~ # chmod 4711 test
chmod: changing permissions of 'test': Permission denied

Finally figured it out, it seems that the install cd booted with a hardened kernel which had chroot chmod restriction enabled. Disabled it in /proc/sys/kernel/grsecurity/chroot_deny_chmod and now it's working.
