emerge udev will break the system in creation of devices in /lib/udev. As I can see the ebuild create the devices and will do a cp .../zero /lib/udev. The result if the device exist is a loop or if it not exist is a disk full. Is a new coreutils (5.2.1-r7 tyed 5.94-r1 also) bug?
Created attachment 83904 [details] my emerge info
I don't understand. What exactly are the errors that happen when you merge the udev package. And what version of udev are you merging that causes this problem?
(In reply to comment #2) > I don't understand. What exactly are the errors that happen when you > merge the udev package. the emerge crash the system in install at diasplay of ">>> /lib/udev/devices/null" line no errors only create a zero file who fill the root partition so i try to run manually mknod /lib/.../devices/null and reemerging udev and at the same point the emerge loop by copy the null device on itself. reemerging libc and coreutils (or downgrade to stable) not solve the problem > And what version of udev are you merging that causes this problem? sorry, 087, I not remember the previous release because I have resolved in two step: adding an rm .../udev/image/lib/udev/devices/* in ebuild emerging udev manually create null zero and console in /lib/udev/devices remove rm line reemerging udev work fine without errors now. run install /dev/zero test will result in a core dump so I think is a coreutils problem.
I was bitten by this and other things. So let me rant a little. :-) 1) (not related to this bug) My /var partition was mounted "nodev", so I had to remount it (first time this ever happened, I consider this to be a bug in udev or the ebuild), because I got this error: !!!

> Uh, not reproducible here w/ exactly same version of coreutils (but no > selinux). Also I think is related to selinux patch for now, how can be reported to hardened team? The function insinto in the ebuild run an install command to move the devices in /lib/udev/devices? Starting emerge in debug mode not show anything only !!! /lib/udev/devices/zero (not even in audit) later (tomorrow I hope) I try to label files after creation in ebuild and report the result. As requested in previous post I report the old version, was 070-r1 and the new is 087, as found in my logs.
I now looked a little closer at this. AFAICS, this has nothing to do with coreutils. The first time I try to update to udev 087, I get this: >>> Setting SELinux security labels /usr/sbin/setfiles: labeling files, pretending /var/tmp/portage/udev-087/image is / /usr/sbin/setfiles: labeling files under /var/tmp/portage/udev-087/image/ /var/tmp/portage/udev-087/image/etc/hotplug.d/default/10-udev.hotplug: Operation not permitted /usr/sbin/setfiles: unable to relabel /var/tmp/portage/udev-087/image/etc/hotplug.d/default/10-udev.hotplug to system_u:object_r:etc_t /var/tmp/portage/udev-087/image/lib/udev/devices/console: Operation not permitted /usr/sbin/setfiles: unable to relabel /var/tmp/portage/udev-087/image/lib/udev/devices/console to system_u:object_r:lib_t /var/tmp/portage/udev-087/image/lib/udev/devices/null: Operation not permitted /usr/sbin/setfiles: unable to relabel /var/tmp/portage/udev-087/image/lib/udev/devices/null to system_u:object_r:lib_t /var/tmp/portage/udev-087/image/lib/udev/devices/zero: Operation not permitted /usr/sbin/setfiles: unable to relabel /var/tmp/portage/udev-087/image/lib/udev/devices/zero to system_u:object_r:lib_t matchpathcon_filespec_eval: hash table stats: 75 elements, 75/65536 buckets used, longest chain length 1 /usr/sbin/setfiles: Done. --- /etc/ --- /etc/dev.d/ --- /etc/dev.d/default/ --- /etc/dev.d/net/ >>> /etc/dev.d/net/hotplug.dev --- /etc/hotplug.d/ --- /etc/hotplug.d/default/ >>> /etc/hotplug.d/default/10-udev.hotplug -> ../../../sbin/udevsend >>> /etc/scsi_id.config --- /etc/udev/ --- /etc/udev/rules.d/ >>> /etc/udev/rules.d/05-udev-early.rules >>> /etc/udev/rules.d/50-udev.rules >>> /etc/udev/udev.conf --- /lib/ --- /lib/rcscripts/ --- /lib/rcscripts/addons/ >>> /lib/rcscripts/addons/udev-start.sh >>> /lib/rcscripts/addons/udev-stop.sh >>> /lib/udev/ >>> /lib/udev/devices/ There it stops, no keyboard input whatsoever is possible.

I am only using SELinux for learning purposes now, I don't know enough about it to be able to find out.
It's an old selinux issue, see the referenced bug that shows how to properly merge this package if you are using selinux. *** This bug has been marked as a duplicate of 115810 ***
