Description Jiri Jaburek 2022-01-19 13:28:44 UTC 
Description of problem:

$ dnf install brltty-dracut

$ dracut -f   # needed to create the dir

$ restorecon -Rvvn /var/lib/
Would relabel /var/lib/brltty from unconfined_u:object_r:var_lib_t:s0 to unconfined_u:object_r:brltty_var_lib_t:s0


I've added and audit watch rule prior to the directory being created:

type=PATH msg=audit(1642598013.580:95): item=1 name="/var/lib/brltty" inode=67533312 dev=fd:00 mode=040755 ouid=0 ogid=0 rdev=00:00 obj=unconfined_u:object_r:var_lib_t:s0 nametype=CREATE cap_fp=0 cap_fi=0 cap_fe=0 cap_fver=0 cap_frootid=0

not sure if it helps in identifying the process context.

Jarku,

brltty-dracut seems to use /var/lib/brltty, but it is not in the package. Would it be possible to include it so that the directory is created at install time?

It's created by the brltty binary which is called from the dracut. I think the directory should be provided by the brltty package, otherwise there will be leftover directory (upon brltty uninstallation). Interesting that nobody noticed so far.

Fixed in the rawhide (f36).
Comment 4 Zdenek Pytela 2022-01-21 14:37:15 UTC 
Based on previous comments switching the component to assess the resolution for RHEL 9, too.
Comment 7 RHEL Program Management 2023-07-19 07:28:13 UTC 
After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
