I'll refrain from my usual biting comments about the uselessness of asking obscure technical questions of ChatGPT. Instead, I will simply say that this answer is, in a word, incorrect. Please see the thread from the last time someone asked about this message: https://sudoroom.org/lists/hyperkitty/list/[email protected]/thread/ENWQFUXQ7TH2LVC5TQSE2LKW6C2LMDYR/ --Sean _______________________________________________ sudo-sys mailing list -- [email protected] To unsubscribe send an email to [email protected] More options at https://sudoroom.org/lists/postorius/lists/sudo-sys.sudoroom.org/
