  • Saner devconf image format
  • More verbose explanation of why task cannot be seized

FixesEdit

  • Too many mmap-ed files blocked the dump
  • Potential memory corruption when working with IPv6 sockets
  • Overmounted bind mounts could cause restore to fail

  • Incomplete restoration of RO bind mounts options

Deprecated/removedEdit

  • Greedy mode of pagemap (non-root) caused dump to fail (disabled)
