Original GitHub issue: https://github.com/netblue30/firejail/issues/287

Example: My .mozilla, .config/chromium, and .cache directories are symlinks that point to a zram (compressed memory) directory, for speed purposes and to reduce disk writes. On boot and shutdown those directories are synched from/to disk. So my home dir looks like this:

.config/chomium -> /snc/voidzero/chromium
.mozilla -> /snc/voidzero/mozilla
.cache -> /snc/voidzero/cache

When I try to launch firejail firefox:

Reading profile /etc/firejail/firefox.profile
Reading profile /etc/firejail/disable-mgmt.inc
Reading profile /etc/firejail/disable-secret.inc
Reading profile /etc/firejail/disable-common.inc
Reading profile /etc/firejail/disable-devel.inc
Reading profile /etc/firejail/whitelist-common.inc
Parent pid 8167, child pid 8168
Error: invalid whitelist path /home/voidzero/.mozilla
Error: cannot establish communication with the parent, exiting...

What is the recommended way to work with a setup like this? I know that a workaround is to bind-mount rather than symlink, but for boot purposes this is not ideal right now.

I'd appreciate some pointers, cheers.

You need both the link and the original file in your home directory. You need to mount the zram somewhere in your home directory, /home/user/snc for example.

Alright thanks. Perhaps this is useful for a FAQ entry?
