4.4.0-72-generic #93-Ubuntu SMP ; Linux Mint 18.1 Serena \n \
I ran an strace on the command ksh -o vi. I see that /etc/ld.so.nohwcap is no longer supported in later versions of Debian. Also seeing an error with /etc/ksh.kshrc. My question is whether the current KSH (93u+20120801-2ubu) is actually supported in mint moving forward.
