So if we use a counter, what's a sane maximum? Is MAXSYMLINKS in <sys/param.h> the value the kernel uses? 20 seems quite low, I was thinking of a much higher number.
Until very recently Linux seemed to hardcode it to 40: https://github.com/torvalds/linux/blob/v4.1/fs/namei.c#L865 That changed in v4.2 and I'm not sure what it does not, if this is the relevant bit of code it uses MAXSYMLINKS: https://github.com/torvalds/linux/blob/v4.2/fs/namei.c#L1647
