Well after this the next problem you'll be running into is:
#define PATH_MAX 1024 /* max bytes in pathname */
Which I already did inf find(1) because the paths in backups of big
filesystems already bit in like 2011. Talked about it with Jilles, and
got more or less the same answer: You can up the value, but expect
things to break.
Which it did when I only fixed the size in find. It would break in the
program that got the path fed.
Never dared to just up the value, compile kernel/world, install and
reboot. And then see what comes of it.
So IMHO if possible this would need to be extended as well...
