How do I fix the ebuild for app-arch/bzip2-1.0.8-r5, so it respects FEATURES=fakeroot when building a binary package?
Here's what my xpak looks like:

Notice how those five binaries didn't get chowned to root:root like everything else did?
fakeroot is working correctly for almost every other package on my system. The only two that do this are bzip2 and systemd-utils.
It's a minor thing, but is annoying AF to see those five files not owned by root when doing a listing.
bzip2-9999 seems to do the right thing, but I'm out of my depth trying to backport its ebuild.
EDIT: As remarked below, it's a "me" problem, and not an ebuild problem; title edited to reflect.

Additional information and observation:
This is the command I'm using:
| Code: | | james@Two-Spear ~/software/gentoo-target $ PKGDIR=`pwd -P`"binpkgs" emerge --root=root --sysroot=root --config-root=root -vB app-arch/bzip2 |
Upon further experimentation, it turns out that I only have the problem when my target directory root is owned by user james. I tried a bunch of other users, like root, portage, bin, guest, but the only one that exhibited the behavior was james, which is who I'm logged in as when running this.
I did get some permissions errors from emerge when I set it to james:root though:
| Code: |

Update 2: Another way I can make it work is to keep the owner:group of the target root as james:james and change the permissions on it to 777. It then works as expected with only the directory permission (and not its contents) changed.
There seems to be other differences between changing the owner and changing the permissions as well:
1) if I chown root:root root ; chmod 755 root, then obviously it's not writable by portage or james, but the package ownerships are correct.
2) if I chown james:james root ; chmod 755 root, then I get the package bug, but I also get all portage's housekeeping files in root/var and root/tmp (even though I'm using -B):
| Code: |

3) weirdly, if I chown james:james root ; chmod 777 root, then I get some of the housekeeping stuff, but I lose the news-gentoo.* and vdb_metadata* files:

So, I guess its not a problem with the ebuild, so I'll mark it NOTABUG, but I really wish I knew what portage is trying to do here.
Further insights are welcome, of course. |

I don't see a related open bug report, so it's probably worth opening one.

If it's not exclusively self-inflicted, then I will, but I want to understand the problem and offer a patch with the report. This situation is a bit of a corner-case, so I'm wary of assuming I'm not doing something wrong.
Why is this ebuild so special? Why is it only those five files in /bin and /usr/bin? How and/or why do target-root permissions interact with portage in general? Stuff like that is relevant to me. |

I wouldn't guess that it's an ebuild problem but rather something handling the fakeroot portion.
The eclass subdirectory doesn't have much: | Code: | $ grep -ri fakeroot eclass/
eclass/tests/rebar_fix_include_path.sh:EPREFIX="${tmpdir}/fakeroot"
eclass/tests/rebar_remove_deps.sh:EPREFIX="${tmpdir}/fakeroot"
eclass/tests/rebar_set_vsn.sh:EPREFIX="${tmpdir}/fakeroot" |
So I'm guessing if there's a bug, it's deeper in portage code. | Code: | grep -lri fakeroot /usr/lib/python3.12/site-packages/ |wc -l
39 |
So unless you're somehow using the feature incorrectly, it seems like a more notable problem.
What are you doing that produces the error. I'm wondering how complicated it is to try and repeat the problem. In the event of a bug report, I'm guessing they'd too would ask that question.

To reproduce the problem, I use two scripts and two directory trees:
| Code: | setup.source
mkpkg.sh
config/
package.use/
|
I also have a local repository with fixups for any ebuilds which fail this and other related scripts, but it's not relevant to bzip2.
Here are my scripts:
This one is sourced by the second one (I have other scripts that use it too):
| Code: |
#!/bin/sh
# setup.source
# Don't use $PWD. emerge can fail with symlinks in the --root=<path> option.
# Use an absolute real path, a relative path, or `pwd -P`.
MYROOT=root
MYCONFIG=config
MYPKGUSEDIR=package.use
# get the canonical package atom of the last argument (@sets pass through unchanged):
for lastarg in $@; do :; done
MYATOM=`echo ${lastarg} | sed -e '/^@/!d'`
[ ! ${MYATOM} ] &&
MYATOM=`emerge -q1p ${lastarg} | grep -o -e '[[:alnum:]-]*/[.[:alnum:]_-]*'`
# strip the version part, from back to front.
# see https://projects.gentoo.org/pms/8/pms.html#x1-250003.2
MYPATH=`echo $MYATOM | sed -E -e '
s/\-r[0-9]+$//
:x
s/_alpha[0-9]*$//
s/_beta[0-9]*$//
s/_pre[0-9]*$//
s/_rc[0-9]*$//
s/_p[0-9]*$//
tx
s/\-[0-9]+(\.[0-9]+)*[a-z]{0,1}$//
'`
#### DEBUG
#echo MYROOT = $MYROOT
#echo MYCONFIG = $MYCONFIG
#echo MYPKGUSEDIR = $MYPKGUSEDIR
#echo MYATOM = $MYATOM
#echo MYPATH = $MYPATH
#exit 0
#### DEBUG
# the dot copies the _contents_ of $MYCONFIG into $MYROOT, instead of making a _subdirectory_ named $MYCONFIG, if $MYROOT already exists.
cp -R $MYCONFIG/. $MYROOT/
# copy any existing package.use file for the target package into the root:
cp -R "$MYPKGUSEDIR/" "$MYROOT/etc/portage/"
#[ -d "$MYPKGUSEDIR/$MYPATH" ] && {
# mkdir -p "$MYROOT/etc/portage/package.use/$MYPATH/"
# cp "$MYPKGUSEDIR/$MYPATH"/* "$MYROOT/etc/portage/package.use/$MYPATH/"
#}
|
This one builds the target(s) into the root, and saves the autounmask output for posterity:
| Code: |
#!/bin/bash
# mkpkg.sh
# ~~~~~~~~~~~
# Create a skeleton root and emerge the given pkg into it from the running environment.
# No chroot, no root required, as long as all the bdeps are installed into the build environment.
#
# The script creates $MYROOT and $MYPKGDIR if they do not exist, and configures portage from $MYCONFIG.
# Note: $MYPKGDIR must be an absolute path, otherwise emerge tries to write something in the build
# environment, which fails with a read-only error if not run as root. Also, if it is run as root, it
# sometimes fails with errors about invalid binpkg.
#
# Usage: ./mkpkg.sh [options] pkg
# emerges pkg with the given additional options
#
# Options are useful if you want to override some default programs. For example:
#
# ./mkpkg.sh eudev vim @system
#
# will install @system with eudev instead of udev, and vim instead of nano.
#
# Note: passing -p breaks the autounmask generation.
#!!!!!
# whatever we pass to --root MUST be a real path (no symlinks!!!). I had weird failures because I specified MYROOT=$PWD/root, which expanded to /home/james/software/gentoo-target/root, but software was a symlink to /mnt/software, which was a partition mount:
# * Package 'sys-libs/libcap-2.69' has internal collisions between non-

| Also, AFAICT: when the target root/ is world writable, emerge demands superuser access for any command that doesn't specify -B or -p. In particular, my script will fail the mode 777 test I manually ran above. No idea why world writable status is special. |

Wow. That's rather involved. I thought this was something portage handled with little fuss. 777 permissions seems very wrong, and I don't see any Gentoo documentation on using fakeroot.

Most of the scripting is just to set up a clean minimal target root before building whatever package you want. I just got tired of always retyping all that stuff. The real meat of it is the emerge call in post #2 above, where we set all the directory values.
The 777 thing was completely an accidental discovery; I was trying to get fakeroot to set root UID and GID on all the files, and I thought 777 would at least let it do whatever it needed to. I didn't think emerge itself would choke on it. |
