Original GitHub issue: https://github.com/netblue30/firejail/issues/5162

Description

The presence of private-lib directive in transmission-common.profile causes jailed transmission-gtk to take a long time to start, seems to add an extra 10 seconds or so to the startup time.

Steps to Reproduce

Steps to reproduce the behavior

$ firejail --noprofile --private-lib transmission-gtk
Parent pid 15113, child pid 15114
Standard C library installed in 2.13 ms
Firejail libraries installed in 5.82 ms
Program libraries installed in 31.40 ms
GdkPixbuf installed in 15.13 ms
GTK3 installed in 18.06 ms
Pango installed in 0.01 ms
GIO installed in 6.68 ms
Installed 159 libraries and 5 directories
Child process initialized in 102.13 ms

Expected behavior

$ firejail --noprofile transmission-gtk
Parent pid 15158, child pid 15159
Child process initialized in 13.38 ms

Parent is shutting down, bye...

Actual behavior

transmission-gtk taking way too long to start.

Behavior without a profile

transmission-gtk starts at ~about the same speed as un-jailed transmission-gtk

Additional context

Looks like ignore private-lib is already set for transmission-qt.profile.

Environment

Fedora 36
firejail 0.9.66

Checklist

The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
I can reproduce the issue without custom modifications (e.g. globals.local).
The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
The profile (and redirect profile if exists) hasn't already been fixed upstream.
I have performed a short search for similar issues (to avoid opening a duplicate).
I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

Do you have a slow driver (i.e. HDD)?

This slowdown in also the case for other private- options like private-opt because the copy the files (instead of bind mounting them).
