Trying to track down a bug in IPP printing
(https://bugzilla.redhat.com/show_bug.cgi?id=1653276).
We're down a rabbit hole where it seems that in Fedora 29
/etc/nssswitch.conf ought to be a symlink. This machine has been
upgraded from F28 and this is not the case. AFAIK I have never edited
the file.
/etc/nsswitch.conf is owned by glibc. It is not a symbolic link as we
ship it.
If find out which packages replaces our configuration with a symbolic
link,
It's authselect.
# rpm -qV glibc
....L.... c /etc/nsswitch.conf
# ls -l /etc/nsswitch.conf
lrwxrwxrwx. 1 root root 29 Nov 18 04:58 /etc/nsswitch.conf ->
/etc/authselect/nsswitch.conf
My clean F29 installation had no such symbolic link, has to "authselect
select --force ..." to force the creation of the link.
The non symlinked /etc/nsswitch.conf even had the header:
# Do not modify this file manually.
# If you want to make changes to nsswitch.conf please modify
# /etc/authselect/user-nsswitch.conf and run 'authselect apply-changes'.
So, was it generated at some point by authselect and not as symbolic link?
Note: Today I got new update for authselect (1.0.2-1.fc29)
There is another thing I found wrong. The backed up nsswitch.conf has
these lines appended (ckey and incomplete aliases line) after the real
end of the original file (aliases: files):
aliases: files
ckey: files
aliases: fil
I can repeat this bad backup indefinitely:
1) check current nsswitch has no such lines
2) run authselect select --force ...
3) backup at /usr/lib/authselect/backup/<timestamp>/nsswitch has the
appended lines
