Broken symlinks

[unformatted]

I'm on a RPi4 with armv7 and LXDE installed. I'm following the system maintenance instructions on the arch wiki where I come to the "Broken symlinks" section. To quickly find broken symlinks I should do:

$this->bbcode_second_pass_code('', '
# find / -xtype l -print
')
but that tries to go into the /net directory where my NAS is mounted, so I excluded that by using:

$this->bbcode_second_pass_code('', '
# find / ! \( -path /net -prune \) -xtype l -print
')
Now I get the following output:

$this->bbcode_second_pass_code('', '

Then the wiki says "Then inspect and remove unnecessary entries from this list.". I have no idea where to start considering this very long list. I checked on a couple of other Pi's and it gave similar (long) output. What am I missing here? Should I exclude some directories and if so, which ones?

[ufo6000]

exclude also /run and /proc

Thanks, that narrows it down to:

$this->bbcode_second_pass_code('', '
[user@PC11 ~]$ sudo find / ! \( -path /net -prune \) ! \( -path /proc -prune \) ! \( -path /run -prune \) -xtype l -print
[sudo] password for user:
/etc/systemd/system/multi-user.target.wants/org.cups.cupsd.path
/etc/systemd/system/multi-user.target.wants/autofs.service
/etc/systemd/system/sockets.target.wants/org.cups.cupsd.socket
/etc/systemd/system/printer.target.wants/org.cups.cupsd.service
/home/user/.mozilla/firefox/6pgwn1ah.default/lock
/usr/lib/thunderbird/hyphenation
/usr/lib/thunderbird/dictionaries
')
I have firefox and thunderbird and cups printing service installed so I have to investigate why they are listed as broken. Recently I had autofs removed so that's truely broken.

[ufo6000]

regarding cups,
a year ago: "Cups systemd socket and service files have been renamed by upstream decision."
https://wiki.archlinux.org/title/CUPS/T ... 72b0140e-1

[unformatted]

Thanks for the cups link, missed that but it turned out that the "old" org.cups.cupsd stuff was already disabled and the "new" cups service was already active so I only had to remove the broken symlinks.

I removed all others as well and rebooted. Printing works, when firefox and thunderbird are started and I run the find command, then both the /home/user/.../lock files are listed. If I close both firefox and thunderbird only the firefox lock file remains listed after running the find command again. I guess that's normal behaviour then, I also tested that on 2 other Pi's and same result.
