I have discovered that in some version of Linux prior to the one I am on the name of a device file created dynamically has changed. Rather than just deal with the latest version of Linux, I ought to support the old way of Linux. Is there a canonical way of handling this sort of change in Rust code.
So for example, the dynamically created file that used to be called:
is now called:
Can you just write a function which checks the linux version (e.g. by invoking
uname --kernel-release) and returns the correct path for that version?
Otherwise if you know the name change is consistent, you could check the new form and fall back to the older one if that doesn't exists.
If you want a version check, I'd recommend calling
uname() directly, rather than invoking a new process.
I never knew
uname was a syscall. I always thought the
uname program used some sort of black magic to discover kernel information.
