Description of problem: I followed the steps for installing guix, provided at https://www.gnu.org/software/guix/manual/html_node/Binary-Installation.html, which include: - Download guix - unpack in tmp - move to /var/guix and /gnu - run guix-daemon as service Doing so causes the service to fail to start and selinux complains. While guix is not provided as a package in fedora, it would still be very useful if it worked well with fedora and selinux out of the box, or, some documentation on how to make it work. Following the steps in the selinux troubleshooter to install custom policies do work, so it is admittedly not too big a deal though. SELinux is preventing systemd from 'open' accesses on the file /gnu/store/gj2i5xs7nm80mwrb139pa8iqfccw08zz-guix-0.12.0/lib/systemd/system/guix-daemon.service. ***** Plugin restorecon (99.5 confidence) suggests ************************ If you want to fix the label. /gnu/store/gj2i5xs7nm80mwrb139pa8iqfccw08zz-guix-0.12.0/lib/systemd/system/guix-daemon.service default label should be default_t. Then you can run restorecon. Do # /sbin/restorecon -v /gnu/store/gj2i5xs7nm80mwrb139pa8iqfccw08zz-guix-0.12.0/lib/systemd/system/guix-daemon.service ***** Plugin catchall (1.49 confidence) suggests ************************** If you believe that systemd should be allowed open access on the guix-daemon.service file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'systemd' --raw | audit2allow -M my-systemd # semodule -X 300 -i my-systemd.pp Additional Information: Source Context system_u:system_r:init_t:s0 Target Context unconfined_u:object_r:user_tmp_t:s0 Target Objects /gnu/store/gj2i5xs7nm80mwrb139pa8iqfccw08zz- guix-0.12.0/lib/systemd/system/guix-daemon.service [ file ] Source systemd Source Path systemd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-225.11.fc25.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.9.14-200.fc25.x86_64 #1 SMP Mon Mar 13 19:26:40 UTC 2017 x86_64 x86_64 Alert Count 1 First Seen 2017-03-20 18:22:18 PKT Last Seen 2017-03-20 18:22:18 PKT Local ID 071e3f3e-fd80-4626-a0a6-0a561bb9239a Raw Audit Messages type=AVC msg=audit(1490016138.843:6012): avc: denied { open } for pid=1 comm="systemd" path="/gnu/store/gj2i5xs7nm80mwrb139pa8iqfccw08zz-guix-0.12.0/lib/systemd/system/guix-daemon.service" dev="dm-0" ino=2627026 scontext=system_u:system_r:init_t:s0 tcontext=unconfined_u:object_r:user_tmp_t:s0 tclass=file permissive=0 Hash: systemd,init_t,user_tmp_t,file,open Version-Release number of selected component: selinux-policy-3.13.1-225.11.fc25.noarch Additional info: reporter: libreport-2.8.0 hashmarkername: setroubleshoot kernel: 4.9.14-200.fc25.x86_64 type: libreport Potential duplicate: bug 1324650
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. 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 EOL if it remains open with a Fedora 'version' of '25'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 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 this bug is closed as described in the policy above. 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 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 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. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
I can confirm this is still a bug on Fedora 30. I tried installing Guix today and ran into the same issue, where SELinux blocks guix-daemon from executing: Relevant Logs: May 03 01:52:02 localhost.localdomain audit[1]: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=guix-daemon comm="systemd> May 03 01:52:02 localhost.localdomain audit[4610]: AVC avc: denied { read } for pid=4610 comm="(x-daemon)" name="current-guix" dev="dm-1" ino=1707509 scontext=system_u:sy> May 03 01:52:02 localhost.localdomain systemd[4610]: guix-daemon.service: Failed to execute command: Permission denied May 03 01:52:02 localhost.localdomain systemd[4610]: guix-daemon.service: Failed at step EXEC spawning /var/guix/profiles/per-user/root/current-guix/bin/guix-daemon: Permiss> -- Subject: Process /var/guix/profiles/per-user/root/current-guix/bin/guix-daemon could not be executed -- Defined-By: systemd -- Support: https://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- The process /var/guix/profiles/per-user/root/current-guix/bin/guix-daemon could not be executed and failed. -- -- The error number returned by this process is ERRNO.
