After updating coreutils you may encounter a problem using touch. This problem often manifests itself as a loop while trying to update other packages:
* Touching gcc/cstamp-h.in * touch: setting times of `gcc/cstamp-h.in': No such file or directory * make: *** [gcc/cstamp-h.in] Error 1 * Touching gcc/cstamp-h.in * touch: setting times of `gcc/cstamp-h.in': No such file or directory * make: *** [gcc/cstamp-h.in] Error 1 ...
or a one-off event that breaks the merge:
touch: setting times of `config.h.in': No such file or directory make: *** [config.h.in] Error 1 emake failed * ERROR: sys-process/psmisc-22.12 failed (compile phase): * (no error message) * * Call stack: * ebuild.sh, line 56: Called src_compile * environment, line 2663: Called die * The specific snippet of code: * emake || die * * If you need support, post the output of 'emerge --info =sys-process/psmisc-22.12', * the complete build log and the output of 'emerge -pqv =sys-process/psmisc-22.12'. * The complete build log is located at '/var/tmp/portage/sys-process/psmisc-22.12/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/sys-process/psmisc-22.12/temp/environment'. * S: '/var/tmp/portage/sys-process/psmisc-22.12/work/psmisc-22.12' >>> Failed to emerge sys-process/psmisc-22.12,
This problem occurs on systems running kernels older than 2.6.22, where futimesat was introduced. This pops up a lot on my older Gentoo VMs for obvious reasons (wouldn't it be nice if we could have an up-to-date stable xen-sources package one day?).
You have four options:
Upgrade your kernel - this is the ideal solution but in an ideal world we all live forever and make too much money.
Disable sandbox - sandbox is intended to soften poorly written scripts. simply add -sandbox to your FEATURES variable. Not a big fan of this solution.
Replace touch with busybox's implementation - this is a neat trick but I have encountered problems using bb's touch in place of coreutils and the next time you update the symlink may get wiped out.
# rm /bin/touch && ln -s /bin/bb /bin/touch
Mask versions of coreutils newer than 8.5 - this is the ideologically correct way to take care of things if upgrading the kernel is not in your cards today.
# echo ">=sys-apps/coreutils-8.6" >> /etc/portage/package.mask
It's important that you remember to remove the mask once you do. Funnily enough, if you have already installed coreutils-8.6+ emerging 8.5 will fail due to the broken touch, in this case you may wish to temporarily use one of the other solutions to get it installed:
