pctrack fails with kvm_nlist: No such file or directory
Added by tuxillo about 1 year ago.
Updated about 1 year ago.
Description
As reported by kworr, it seems pctrack(8) does not work:
# pctrack
pctrack: kvm_nlist: No such file or directory
- Status changed from New to In Progress
It only works for kernels built with DEBUG_PCTRACK. The program itself should warn instead of just spit that error.
Definitely works when kernel is buitl with DEBUG_PCTRACK:
