How to specify the path of the firejail.config file？

[smartfind]

I have a need for migration in my business, but I have found that once Firejail is compiled, I cannot re specify the Firejail.config path, resulting in the Firejail.config file not being found. Is there any good solution?

• re-compile
• symlink
• submit patch and wait for release

Hello, is there currently a direct way to specify the firejail.config path?

[rusty-snake]

No:

firejail/src/firejail/checkcfg.c

Line 68 in 66a2818

const char *fname = SYSCONFDIR "/firejail.config";

Also what do you mean with "to specify the firejail.config path" more precisely? i.e. where/how to specify.

After compiling in Firejail, I need to migrate to another environment for use. If the path stored in the migration environment is different from the path output by the compilation, there will be an error message saying that Firejail.config cannot be found. At this time, I hope to specify the Firejail.config path through a method similar to -- config.

Implementing a command-line switch for the path to firejail.config sound nearly impossible to implement safely.

Well, thank you very much. I do have a need to migrate to any target environment and call any directory here. I will think of other solutions.

While this specific use case may be difficult to support safely, it would still
be helpful to know what kind of environments firejail is being used in, to keep
them in mind when considering the tradeoffs of bumping the minimum supported
version of the kernel/distro/tools/etc.

Would you mind specifying the following for the host and target (taken from
build_issue.md)?

• Name/version/arch of the Linux kernel (uname -srm):
• Name/version of the Linux distribution (e.g. "Ubuntu 20.04" or "Arch Linux"):
• Name/version of the C compiler (e.g. "gcc 14.1.1-1"):
• Name/version of the libc (e.g. "glibc 2.40-1"):
• Name/version of the Linux API headers (e.g. "linux-api-headers 6.10-1" on
  Arch Linux):
