Red Hat Bugzilla – Bug 817088
fakeroot slows down unpacking.
Last modified: 2015-06-29 20:05:09 EDT
Description of problem:
After upgrading my system from fedora 14 to fedora 17 i notice that unpacking files in a fakeroot environment has become extremely slow. So i made a check on may notebook running fedora 16, and i saw the same behavior. Unpacking a file without fakeroot as fast as expected. But as soon as i use fakeroot, i need a lot of patience.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. unpack a file without fakeroot
2. unpack a file with fakeroot
user@host > time tar -xf packages/linux-3.3.tar.xz
user@host > time fakeroot tar -xf packages/linux-3.3.tar.xz
* Both call are executed with same speed
* In Fedora 14 this issue did not appear.
* Fedora 16 and 17 have the issue.
* Disabling selinux did not speedup fakeroot execution.
* Updating fakeroot to 1.18.3 did _not_ solve the issue.
Ok i figured it out: fakeroot is a symlink to fakeroot-tcp. When i use fakeroot-sysv, the speed is back to normal.
user@host foo> time fakeroot-sysv tar -xf package/linux-3.3.tar.xz
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
In Fedora release 19 this problem is still present.
Disabling SELinux does not help. Please advise how to proceed.

This also works here. But why is fakeroot-tcp so slow?
Created attachment 833272 [details]
Add alternatives for faked and libfakeroot-0.so
With this we could give the user the chance to decide if tcp or sysv version is used.
Could the patch be applied for the next release?
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
I'm looking into this, but I need to figure out how not to get dangling symlinks upon package upgrade (fresh install with the patch applied is of course fine).
